**Please don't try this at home**
Place a regular counter-top microwave oven on its back surface so that the door opens "up". Insert into the microwave a specially designed plastic liner that has a series of cylindrical indentations in it. Each indentation is about 6 inches deep and 3 inches in diameter. Into each indentation goes about a half dozen beaten eggs. Close the lid and then cook on medium high for about 2 minutes (this will have to be tweaked). The standing waves generated by the magnetron should unevenly cook the eggs, "curing" certain parts while leaving other parts runny. The liner is then removed and the contents are strained/decanted. What's left (should be) cooked eggs roughly in the form of the pattern of microwaves inside the oven. The ultimate would be scrambled eggs in a sort of reticulated, cylindrical pattern.
Might work for custard too, who knows.-- Gamma48, May 21 2009 Something horrible might happen. [+]-- lurch, May 21 2009 + I don't know about any of this, but you had me with the **Please don't try this at home**!!-- xandram, May 21 2009 Alternatively, microwave the egg in its shell. Serve with pufferfish.-- ldischler, May 22 2009 nice-- dentworth, May 23 2009 Why do you need to flip the oven and add a special liner? Couldn't you do this trick by just disabling the turntable? (This is not a rhetorical question - I'm looking forward to a good clear answer illuminating my ignorance of microwaves and eggs).-- pertinax, May 24 2009 IIRC, this is commonly done with chocolate by just removing the turntable, so I don't see why that method wouldn't work for eggs.-- notexactly, May 27 2019 Nice, I wonder what shadow patterns are formed when candling a microwave shaped cube of 1400 reticulated egg servings.-- wjt, May 28 2019 You candle your eggs after breaking and beating them?-- notexactly, May 28 2019 Yes.
The blob coming out of the microwave, I am imagining here, would be a semi cooked, transparently varying, cube which light can be shined through.On second imaginings, might need an clear retaining vessel.-- wjt, May 29 2019 Admittedly, the candle might have to be a synchrotron light source-- wjt, Jun 01 2019 random, halfbakery
