I'm surprised no one has mentioned inverter microwaves. Unlike plain old regular microwaves where power settings just adjust the time that the magnetron is running at full blast the inverter ones can actually change the power of the magnetron. Makes it tons easier to cook food evenly and calmly. Never am I buying again one without.

It's kinda hard to find them though. Most manufacturers hardly list this but Bosch seems to have inverter in most of theirs. My favourite is the Bosch BFL634GB1. Bosch BFL7221B1 was a huge downgrade due to the shitty touch screen and wheel along with a multi-second boot time.

> It’s about staring blankly at the buzzing white box, waiting for the four dreadful beeps that give you permission to eat.

I thought it was near universal that everybody staring at the microwave was engaged in a game of chicken where you try to open the door as close to zero as possible while preventing the beeps.

The beeps must not sound.

I have no idea why it’s important to prevent the beeps, but it feels like a deep primal compulsion. Our ancestors must have learned that the beeps attracted sabretooth tigers or something

Just be careful doing this if there’s a radio telescope nearby:

However, about 25 FRBs detected mainly by the Parkes Radio Telescope and a few other observatories presented signatures that were very different. Although they covered a wide frequency range just like the other FRBs, the frequency-time structures of many of these events defied any physical model, and they did not show differences in the arrival times between the higher frequencies and the lower frequencies of the burst. Also, the location of these FRBs was difficult to pinpoint; the radiation seemed to come from all directions. The Parkes astronomers, mystified, dubbed these "abnormal" FRBs "perythons" after a mythical figure invented by the Argentinian author Jorge Luis Borges. The perythons’ signatures caused astronomers to doubt the extragalactic origin of FRBs [PDF] althogether. They might originate on or nearby Earth, the scientists began to believe, and some astronomers even suggested that these strange bursts might be produced by extraterrestrial civilizations.

Not long after focusing their attention on the perythons, the Parkes astronomers noticed that these FRBs seemed to take off during weekends. In 2014, they installed a radio frequency interference monitor at the observatory and decided that the culprits were probably some microwave ovens inside the observatory building. Tests with these microwave ovens yielded nothing—they emitted no radio pulses while they were running. The astronomers were flummoxed—that is, until one of the testers, during a third attempt, opened the door of a microwave oven before the magnetron was shut off by the timer.

I know it's silly, but I always used to open the microwave door to stop it, and since reading that story, these days I always stop the microwave with the 'stop' button before opening the door. Just in case. :)

I completely agree in the game of chicken. Usually I spend the time up to T-3s wondering how the crazy beepers on microwave ovens is still a thing, generations after the novelty has worn of.

I can sort of understand why beepers where a cool sales gimmick back when the microwave was the only appliance with a micro controller, but really -- it doesn't make sense: Firstly, immediate attention is not critical when the time is up: unlike a stove or an oven, energy transfer stop the moment the magnetron is de-energized. Secondly, the microwave (at least my microwave) is not exactly silent: if you are not deaf, chances are you can easily tell when it is done.

Maybe I should apply the Joe-treatment from my old lab: whenever there was a new shipment of frequency meters for the lab (we always needed more), Joe would meticulously unbox them and stick a pointed screw-driver through all the piezo buzzers to make sure the would never make a sound.

Removing an offensive buzzer or beeper or overbright LED is far more satisfying. Plus, nobody can trivially unmute the thing.

But that said, I wouldn’t mind a microwave that could be quieted without completely muting it. They could mute the buttons but still let it beep once when a timer or cooking cycle finishes. On the other hand I have a phone that I can time things with, so I’m not really looking to replace my microwave merely for that.

> The actual recipe section starts with the recipe for a bowl of cereal, which I am 70% sure is a joke

For years, I would get up insanely early and be the first in the office, with no-one around other than the cleaners. My breakfast every day would be microwave-cooked oats - but it wasn't quite as easy as the recipe from the book makes it out to be, mostly because of the milk.

Unlike water, when you heat up milk to a high temperature in the microwave, it behaves just like it does on the stove top: it wants to crawl out of the container and nicely spread itself everywhere.

So, I developed sort of a technique that consisted of short bursts of microwaving at full blast, then stopping and stirring, and back in with bowl. I repeated that a few times, but after I had the technique down, it didn't require much attention any more, it worked quite reliably.

The oats got cooked nicely, and thanks to the pectin of an apple that I also added in, it also thickened. (And in case you wonder, the apple's acidity does sometimes split the milk somewhat, but in most cases it doesn't.) However, there's definitely a difference in smoothness between microwaved oat meal and one that's made slowly on the stove top - the latter being much nicer in texture.

But it was a quick breakfast that I really enjoyed (with a dash of cinnamon) at my desk every morning while I was going through my email from the night before.

Every microwave I’ve ever looked at from a distance, or actually used, has the ability to set the power level, typically in 10% increments.

The typical workflow is: power button > number button 1-9

My daily driver is a bit more fancy, and has a single button to cycle through the available power settings.

For your milk oats I’d suggest a power setting around 30 to 40% and increasing the cooking time by a factor of 2.

kleiba45 minutes ago

Sure, but you want to go as hot as possible to get the oats cooked. Besides, I wanted to be as quick as possible. Like, quick oats, you know? ;-)

I'd never make porridge with water at home - but in winter in the office I used to cover a 1/3 bowl of oats with boiling water and then microwave for just 30 seconds.

Once the oirriois cooked (it really should be already) add a teaspoon or two of salted butter to the middle and stir, then sugar to taste.

Suprisingly delicious, quick and repeatable.

I won a few people over who couldn't believe that porridge made with water would be any good, but it was a great winter staple, especially after cycling in, in the cold.

In 1986 I briefly lived in a squat in North London, and the gas had been disconnected. We cooked everything in the Microwave, and we ate nutritious and completely unexpected (to me) normal meals, like Lasagne made with dried pasta, which uses cottage cheese to boost the moisture content so the sheets of Pasta soften. I appreciate at this point some people are saying "normal??" but truly, compared to the alternatives, using a more liquid cheese to make a meal which conforms in all other respects to your expectations, was huge.

(gas reconnection was hard. Electricity, for reasons I never entirely understood, was easy to get reconnected to squats, at the time)

My co-occupants had a lot more experience than I of this life on the edge. I learned a lot.

The skillet sounds cool but I'd rather not have to deal with a microwave door and control panel for searing stuff. I do, however, frequently use it in ways that others find unconventional:

- Cooking dry goods (quinoa, freekeh, couscous)

- Single-serving coffee mug surprises (omelettes, protein brownies)

- Low-carb cheese crisps (via parchment paper)

- Not-fried rice (day-old rice, light sesame oil, soy sauce, bits of egg, leftover veggies, random seasonings)

- Frozen breaded chicken (wrap really well in paper towels to absorb moisture, overshoot on time, unwrap as soon as they're out to avoid sticking - they come out like 66% as crispy as using a convection oven)

I do draw the line at pasta because the texture never seems quite right when you boil it in the microwave.

For pasta: you can make it fresh so it only needs 2-3 minutes to cook, boil water in the microwave, and cook the pasta itself in that heated water (ie, on the counter as it cools from boiling). Like making instant ramen, but fresh pasta — throw in a stock cube and you can serve in the bowl you cook the pasta in.

I’m suddenly in desperate need of a pyroceram skillet too. I’d love to be able to make proper cheeseburgers with grilled onions one at a time without using a stove or grill.

Yeah, I now need a pyroceram skillet too!

But as the solo meat-eater human in my apartment, I ended up buying a gas-canister camping grill to barbecue steaks on my terrace on weekends and then I reheat the rare steaks through the week in the microwave. They get the Maillard reaction and flavor, they get to the correct doneness point when blasted with RF later on.

Cats get happy with the barbecuing, I also grill mushrooms and tofu for my wife and it’s very easy to clean afterwards.

>Pyroceram is a specialized,, white or slightly amber-tinted, opaque glass-ceramic developed by Corning in the 1950s, known for extreme thermal shock resistance and high-temperature tolerance up to 1292 ∘ F It has near-zero thermal expansion, making it ideal for cookware, cooktops, wood stove doors, and, historically, missile nosecones.

Didn’t expect the missile nosecone.

dsr_1 hour ago

Inbound anecdote.

Dad worked for Corning; when they hired him, he bought a house one town over. It came with a Corning electric range in the kitchen. This was effectively four electrical resistance grids embedded in a giant sheet of pyroceram.

Like an induction cooktop, there is no visible indication that the "burners" are "lit", unless you looked at the control panel off to the side.

Somewhat like an induction cooktop, only certain cookware was compatible with it. Luckily, the primary requirement was "the bottom needs to be flat". You might be surprised at the number of pots which have concave bottoms... or develop them over time.

UNlike an induction cooktop, it does get up to arbitrarily high blackbody temperatures.

Pretty much every accident you can think of synthesizing from these conditions occurred. Nobody in my family would ever buy one. (I love lots of other Corning products.)

Oh, and as for the easy-to-clean surface? Very true... as long as you ignore the case of scorched proteins. Anything else, you wait for everything to cool and then wipe it with a slightly soapy sponge, then mop with a damp cloth. I don't remember the night the grey scorchmark appeared, but it lasted about fifteen years. Then Dad sold the house.

The microwave has two big related issues (both mentioned in the article).

The first is that it is not easy to make a mental model of how it works. The second is that since it takes little too cook the food, it is unforgiving and you have to be very careful with both timings and amounts.

This makes it hard to learn how to properly use it just by trial and error. Also since now we have inductive stoves there is even less reason to use it.

schiffern2 hours ago

I feel like 80% of the microwave's downfall was adopting VCR-like push button interfaces.

The two dial microwave was peak UX. Quick, painless, no wondering what sequence to press on a strange 'wave, zero time delay between input and cooking, and easy use of the (essential) power function.

It even lets you change time or power mid-cook. For maximum laziness it's possible to leave the door cracked with time on the dial, throw in the food, and adjust the dial while it's already on (slightly reducing the wait before eating). Using the microwave becomes forgiving instead of foreboding, because it's so easy to change your mind.

The only downside is that it's slightly less precise, but getting the exact time down to the second is probably less important than you think. It's also a mechanical part to fail, but I've had microwaves die because the push buttons failed too, whereas my dial unit is still going strong. YMMV

leoedin1 hour ago

There are some use cases where exact time is very important. Warming milk for a baby for instance - it’s pretty low volume and the difference between 30s and 40s is huge. I used to favour the 2 knob microwave, but since having to do that a lot I’d always choose a digital timer. Some have decent interfaces.

danw19792 hours ago

We are repeating this same UX mistake with induction hobs now.

schiffern2 hours ago

I noticed, it's an unfortunate regression.

What's amazing is how the vibe of using the microwave completely changed. Before it was:

"Okay, how much time?? I've gotta get this right, I only get one shot. Think!!"

to:

"Probably 2 minutes." moves knob, cooking starts "Eh, maybe 90 seconds actually." moves knob again

That alone probably reduces the error rate, and it certainly reduces annoyance.

With the new stoves, I've noticed people are starting to dread using their stove the same way they dread the microwave. Hopefully we can fix both.

IshKebab1 hour ago

At least there's a good reason there - they're easier to clean. That's not much of a concern with microwave controls.

But I disagree with the idea that we don't need precise times on a microwave. The article / book disagrees with that, and the think I most regularly microwave (milk for my kids) needs 1 minute 50 seconds. 2 minutes and they'll reliably complain it's too hot.

The real problem with microwave UX is that the interfaces are often simply bad. People think the power/time dial interface is good but that's because it's difficult to mess it up (though they usually manage anyway by having them go up to 30 minutes or whatever).

It's really easy to mess up a button interface but you can also do it well. My microwave is close to doing it really well. You press a high/med/low button, then 1s/10s/1m/10m buttons to the desired time, then start. The only things they got wrong are that it requires pressing the power when 99% of the time you want high, and you could probably get a more useful distribution of time increments (I'm literally never going to use the 10m button).

But apart from that it's nicer than dials, which are often very cheap and imprecise.

schiffern26 minutes ago

  >they're easier to clean
I've never had an issue cleaning the dials. They're smooth hard plastic, and they don't get particularly dirty.

  >though they usually manage [to mess up the interface] anyway by having them go up to 30 minutes or whatever
What's the issue? I've microwaved things that long before.

  >My microwave is close to doing it really well. You press a high/med/low button, then 1s/10s/1m/10m buttons to the desired time, then start.
That UX sounds awful; one of the worst I've heard of (and unfortunately, encountered).

Enter time on the keypad, optionally press Power and enter that, press Start. Also needs a Plus 30s button. This is the one and only correct way to implement a push button microwave. ;)

  >needs 1 minute 50 seconds. 2 minutes and they'll reliably complain it's too hot.

The dial microwave I've used can distinguish between those two. It helps that the shorter times are given more room, so you can adjust them more precisely. 1:50 vs 2:00 will make a difference in my experience, but 7:50 vs 8:00 generally won't.

You could have a hybrid approach of course, but then I suspect the engineering tendency would be to "lock in" the time after starting the oven, so it can't "accidentally" be changed.

Looking for a photo of my microwave dial, I came across this surprisingly relevant post:

Up voted for basic commercial unit recommendation.

I have one of Panasonics upper model flatbed microwaves that also acts as a fan forced oven with traditional oven element and fan, and as a grill with two overhead halogen grilling elements.

I picked it up for 50% RRP as it marked down for a minor defect I can’t even recall.

It’s 1900 watt on full microwave power, if I recall correctly, where most on the market amend here are 1400 watt. Makes a lot of difference, browning the top of food is easy with a bit of oil.

I can’t really fault it, it’s super easy to keep clean and works great for baking where using full size oven is overkill.

So this can only do the full 1000 W power? Kind of a one trick pony, no way to melt butter or a dozen other things that need lower power. For a restaurant that only needs to heat a few different items at high speed it's probably fine.

nandomrumber4 hours ago

I discovered a (lame) party trick some microwave ovens are capable of.

Many microwaves will let you set the power to 0% by pressing the power button then 0 or 00.

You can then put a cup of hot water from a kettle or the hot water tap in the microwave on 0% power for two minutes and it will come out colder.

Bonus points if you have a thermometer at hand.

gucci-on-fleek3 hours ago

> Does anyone knows if using microwaves might possibly affect the nutritional value of the food?

Cooking in general affects the nutritional value of food—some nutrients are easier to absorb when cooked, so cooking effectively increases their amount, while other nutrients are destroyed [0] [1]. But given that you're probably cooking your food anyways, there's nothing specific to microwaves here.

Microwaves might actually be slightly better than other cooking methods here, since they produce a lower heat that's less likely to destroy nutrients, but the cooking method has such a minor effect that I wouldn't really worry about it either way.

> Or if radiation can leak and affect you body if you stand very close to it while it’s running.

Microwaves are classified as non-ionizing radiation [2], so their main effect is just heating things up. So if you're standing near a microwave and your body starts heating up, then something bad is happening; otherwise, you're probably fine.

The only health risk from microwaves (aside from a hypothetical accident involving someone being cooked inside one like a rotisserie chicken) is cataracts [3]. But this usually only affects radio technicians, who put their heads beside much bigger and much more powerful microwave emitters than a domestic microwave oven. And even cataracts are only due to the heating effect.
