Yes! In 1969, the physicist Nicholas Kurti gave a talk in which he demonstrated a variant of Baked Alaska called "Frozen Florida": a shell of frozen meringue around a center of hot liquor. This was done by chilling the meringue and the liquor together, then cooking in a microwave oven which had a rotating platter and no stirring fan. Because the microwave ...

The piece of cardboard is a microwave browning element. Ordinarily, most of the heating energy in a microwave is absorbed by water in the food. The result is similar to steaming. The material on the cardboard is designed to absorb microwave radiation and convert it into heat, attaining a higher temperature than boiling water would reach, to allow the bottom ...

Microwave doors don't have an airtight seal; the window between the electronics and the cooking compartment is also not airtight, and the electronics are cooled by a fan. It would be surprising if some cooking smells didn't escape. In practice, every microwave I've ever had allows me to smell the cooking, from the very cheapest to some rather fancy ones with ...

There is one very different issue to be kept in mind - water in a microwave can overheat and "explode" once it is disturbed. Another poster had exactly this problem a short while ago: Water exploded in Microwave So follow the usual precautions, e.g. putting a wooden toothpick or a small, very clean stone (chemists have them in their labs) in your vessel. ...

This probably refers to whole eggs mostly... A microwave can boil water very rapidly, and a tight but fragile container like a whole egg will violently rupture if such rapid boiling happens inside it, because the overpressure inside it is already significant when the shell finally breaks. Here is a video showing an experiment with ca. 180 eggs in a ...

Metal has a lot of potential issues in the microwave (electric charge buildup + arcing, and microwave reflection). There are too many variables to make general statements like "such-and-such metal is safe" or "smooth objects are safe" with confidence, hence the sweeping guaranteed-safe blanket advice to not put metal in the microwave. The reason it didn't ...

I think the primary considerations are convenience (how much effort is it to set up and use the system?) and time spent (how long does the system take to heat the water?). A standard electric stove can have 2500W elements, and most of this energy will go into a kettle sitting on the element and thus heat the water. Even a big built-in microwave won't be ...

After I found the pack of microwave popcorn again I decided to do a quick search on the English web. I found that the corn in the bag is just normal popcorn mixed with some fake butter and that there'd be no issues popping it on the stove. Then I looked for good ways of popping corn on a stove and found an excellent video with step-by-step instructions. ...

Bear in mind that I'm using an electric kettle, rather than a stove-top one. First, the advantage of a kettle is that it is quite efficient, and turns itself off once the water is boiling. This as opposed to the microwave, which only stops after a set time, rather than relying on the condition of the water. Second, a microwave can cause water to superheat,...

Oh lordy. You're lucky you didn't get hurt. Ann Reordan did a good video about these microwave egg hacks. The segment with her many experiments starts around 6:00. (other hacks/myths are at the beginning and end of the video.) https://youtu.be/vdaKrT9x1Zc Short version: it's speculated that the microwave super-heats the interior of the egg and the internal ...

Spoons (most metal, in fact) are generally not a huge problem in the microwave. My microwave has metal parts...many do. Forks are sometimes a problem due to a build up of charge between the tines, which could result in sparks. As you note, shape can be a factor. The shape of spoons spreads the charge, the pointy edges of forks and narrow tines could ...

With all electromagnetic radiation, including visible light and microwaves, absorption depends on the molecules doing the absorption. Air is mainly oxygen and nitrogen, and these don't absorb very well at the 2.4GHz frequency used in microwaves, while foods do. A lot of this is down to the very efficient absorption by water, and almost all foodstuffs ...

As someone who tried this out at a young age, I thoroughly DO recommend it! The microwave makes a huge bang and jumps 2 inches off the bench. Good times! (However, you need to do some heavy duty cleaning before mum gets home.) However, by breaking another rule, you can boil an egg in a microwave. Steps: 2/3 fill a coffee cup with boiling water. Wrap ...

Well, I can tell you with absolute authority that polystyrene melts in the microwave. Here's a chunk of polystyrene cut from a foam shipping container. I double checked with the website (Propak), and the stuff is polystyrene. I placed a random chunk of chicken on the cube, and microwaved on high for 1 minute. So yeah, it melts. Is it toxic if it melts ...

Popcorn should be considered one of "nature's little miracles" - & a way to make a huge profit out of air. Yes, you can pop other dried grains/seeds, but don't expect anything quite so bag-filling as maize. Quinoa, chia, sorghum & amaranth will all pop [in a dry pan, not sure about microwave] See https://www.huffingtonpost.co.uk/entry/...

There are actually two things worth considering with metal in microwaves. The big danger is arcing and that happens with pointy things like forks and apparently grapes. It's also worth considering, being in a plastic box, there was nowhere for the spark to jump to. With a fork there's a small enough spark gap for current to jump. With a spoon, there is not. ...

In 2017 researchers from Charles M. Salter Associates in San Francisco looked into the exploding microwaved eggs. They'd been hired to offer testimony in litigation of a case where a consumer claimed an exploding egg had damaged his hearing, so their focus was on how loud the eggs were, but they also offered a possible explanation as for the reason of the ...

Whenever something gets hot in a microwave, it indicates the presence of water. If something that used to stay cool suddenly heats up, you have water present where previously there was none. I assume you are using a glazed ceramic mug or jar, not one made of glass. Your glazing must have tiny cracks in it, that allow water to reach the clay underneath and ...

The "instant" sponge cake, innovated at El Bulli, can only be made in a microwave. Here is an example. Basically, a batter is poured into a whipping siphon. It is charged. The aerated batter is dispensed into paper cups. The cake is cooked in a microwave. The cups are removed and inverted. The cake is released. It is easy and fun to do.

The spark was a voltage jumping over a gap somewhere. This may occur again, but so long as the magnetron survives, you should be okay. The problem with sparks is they can leave a carbon trail deep inside which is conductive and may actually make the next spark occur at a slightly lower voltage. If this happens enough, you will eventually (or shortly) damage ...

It is impossible to convert Microwaves into Celsius or Fahrenheit. Temperature(Celsius): Temperature is a measure of the average translational kinetic energy of the molecules of a system. Heat is commonly expressed in either of two units: the calorie, an older metric unit, and the British thermal unit (Btu), an English unit commonly used in the United ...

First off, the terminology issue. So, can someone please clear up this fog? What's the difference between Microwave and Oven and Microwave Oven? "Microwave" is just short for "microwave oven". Both terms mean the same thing: an appliance that uses microwave radiation to heat food. Cooking food in this way is called "microwaving". An oven, on the other ...

Your microwave isn't exactly cooking your food from the inside out. Instead, what is happening is that some parts of your food that happen to be on the interior are being heated faster than those parts of the exterior that you observe. This sort of uneven heating is intrinsic with how microwaves work. Microwave ovens cook unevenly because a pattern of ...

Joe is essentially right. Bubbles form in a liquid at what are called nucleation sites - small irregularies in the container or in the liquid itself. If you look at the bottom of some beer glasses, there are little nodules (often in the shape of the brewer's logo) that nucleate bubbles of the CO2 that's dissolved in the beer. Much the same occurs with ...

A simple undamaged raw egg in a microwave at full power will explode. Unless you have a deep desire to thoroughly scrub your microwave I can not recommend that approach. The problem is that the egg will be heated to more than 100C, that means the water will start to vaporize and steam has the nasty habit of needing way more room than liquid, and you get a ...

Consider the humble supermarket pita. The kind with the ridiculously long shelf life. Straight from the packet, it's pretty miserable. It's chewy - not in a good way. It tastes of cardboard. Toast it however, and it comes to life. The slight browning of the outside improves the flavour. The steaming of the inside softens the bread inside. I'll bet the ...

Here is a list of common plastics found in kitchen containers. You will find this information on the bottom of the container, in a triangle with a number inside. While some plastics used in microwavable applications appear to have a high melting point, PET for instance melts at 510ºF, please remember that the material will soften, weaken and otherwise ...

At least for smallish and thin objects, microwaves heat foods “everywhere and throughout at the same time” (for lack of a better description). Exactly what isn’t desired for a steak, as discussed in the Q/A that inspired your question. To achieve similar results of heat distribution with other methods, you either stir the food (for cooking in a pot) ...

It's totally normal to smell the food in a microwave as they aren't meant to be sealed. Microwaves have fans to circulate the air and keep the electronics cool, so they will circulate aromas.

The directions are in fact asking you to place a bowl of water in the Microwave Oven and run it for 10mins. The reason is, it allows things to "break-in" and assures that you don't have any direct issues with the device and that all nasty solvents are given proper time to "burn off." This is so you don't end up with nasty plastic smells and flavors in your ...
