I wonder if there’s a market for a microwave with an IR camera and AI to estimate food weight and thermal conductivity. With accurate heat tracking, it’d only need a button to open the door and no knobs.

Some microwaves take a useful shortcut with a sensor for water vapor, so they know when something has started to steam and can reactively change the amount of time remaining.

Obviously this is great for things like soups, but not-so-much for things which don't reach 100C in an even fashion.

If even one person here doesn't yet have a fast-reading food thermometer I have to evangelize for them here. Good ones that instantly read used to cost like $75, and the cheap kind would take literal minutes to arrive at the real temp, but I think someone in China figured out the secret and brought the price down to like $14. Mine has a magnet and I keep it right next to the microwave and air fryer. It has made it tr…

Completely agree with the reduced power recommendation. That really helps evenly heat foods that start popping in the microwave or have hot spots when taken out. The few extra minutes are usually not a big deal anyway.

Better microwaves existed. Nobody wanted them. Technology Connections:

Earlier quoted context omitted.

I want an IR camera and I want to input my desired temperature. That's all. Then I want the microwave to cycle on when the camera says everything is below temp, and cycle off as soon as any hot spot hits temp. Then wait for the hot spot(s) to dissipate before cycling back on. Seems like a foolproof way to cook evenly without overcooking. I kind of approximate it now by cooking something frozen on high for a couple mi…

If it's going to take 10+ minutes to cook, why not use something like a toaster oven?

Because if the microwave can do it in 10-15 min, the toaster oven is going to take 40-60 min or worse.

Waiting 10-15 min to reheat something evenly is doable for me. I can make a side salad, toast some bread, empty the dishwasher or whatever while I wait.

Waiting 40-60+ min requires real advance planning, which is often just not feasible.

If you've ever used a toaster oven to warm up a frozen personal-size lasagna, sometimes it can take as long as an hour and a half.

In particular, anything that has a lot of liquid benefits from using lower power for longer.

Of course, putting a quart of spaghetti sauce in an open container and microwaving it at 100% will result in some very cool sauce explosions as localized steam in the source rapidly expands and blows giant sauce bubbles all over your microwave.

Yes microwaves can go far through ice but only 15 or less milimeters into water depending on the water's temperature. Microwaves are best for ready to eat frozen foods or reheating leftovers spread out over a plate.

Yeah, the instant thermometers are very nice. Also though, i was recently asked about my favorite nonstandard kitchen appliance and my laser thermometer is my single favorite kitchen gadget, i use it every single time i cook anything. Granted, it reads the surface, but it'll tell you the exact temperature the skillet is at , at every location so you can tell when the cast iron is sufficiently heated to perfect a steak. I prefer my food at about 120°F which is right around the steam point.

Also interesting point related to the article, if i point my laser thermometer at the microwave while it's going it'll bug out and return random temperatures between the actual temperature of the window and about 500°F. I'm sure i could figure out why but i just haven't had the time yet

My parents used to cook taco meat and bacon in the microwave. It worked OK-ish. It's hard to actually get the Maillard process going in a microwave with a couple of pounds of ground cow, so proper browning wasn't a thing. They'd just put the moo into a glass mixing bowl, turn the machine on, and give it rigorous toss with a wooden spoon every couple of minutes. Ground beef crumbles were the result. For bacon, we had…

I actually have one of those bacon tray things. It's just very messy as you say and doesn't really save effort overall. Probably better using a standard oven for big batches. re: ground beef or meat in general, slow cookers have sort of the same problem with respect to Maillard reactions. You're generally better off using a dutch oven, browning, and then cooking in the dutch oven--unless you want to do prep and then…

(I'm straying pretty far from topic, and I for one don't care much. It's still about cooking food, right?)

I think the bacon tray thing I remember was made by Anchor Hocking. I've found them while thrifting and I leave them on the shelf for someone else -- bacon in the oven (or in a cast iron skillet) is just simpler, even including the differences in mess.

Man, slow cookers. My mom gave me one once. As such things were at that time, it was nice: Big, Crock Pot-branded, removable guts, stainless outside, glass lid, one knob, two or three speeds. She still has a big thing for them and was very pleased to give it to me as a gift.

A then-SO persuaded me to donate it during a downsizing. I was a little bit bummed, but then: I recognized that I had never really used it.

That was a decade ago. I've found that I haven't missed it a bit. The only thing it was really good for was shredded chicken sandwiches from locally-canned chicken (which seems to be an Ohio-only thing), and that was something I only ever made one time in my decades of cooking.

Otherwise it was just a glorified food-keeper-warmer, and there's other ways to do that.

I've politely refused other gifts of slow cookers.

But these new-fangled Instant Pots (and their similar kin) are pretty sweet, I think. They don't really do even a quarter of the stuff they're advertised to do, but they're really good at doing things like beans and braised meats fast.

An electric pressure cooker allowed deciding to make a supper of chili with dry beans (another Midwestern thing) became a decision that could be made in the early evening instead of the night before. And with the Keep Warm function, it'll stay at a reasonably-safe serving temperature automatically -- much like the slow cooker's most-useful trick.

Swissed steak (you know, the economical dish that is ideally made with whatever low-grade hunk of cow is on sale cheap today along with some tomatoes and onions)? Fast, proper, spoon-tender, and delicious.

I don't use it as much as I could, but it's always pretty rewarding when I do.

(It's hypothetically no better or safer than a properly-used old-school stove-top pressure cooker, but the automatic timer and temperature/pressure regulation makes proper use a whole lot easier.)

If you're screwing around with microwave sources, I'll pass on a warning I got from one of my profs. Microwaves will heat your body up, but in a relatively harmless way. e.g. If you microwave your hands a bit, blood flow will transfer that heat out and things will remain pretty okay unless you really overdo it. Your eyes are an exception. They're orbs of aqueous humor that's mostly water, but have relatively little b…

What kind of protective goggles can help here ?
