İndispensable for movies, easy to make, ready in 5 minutes with a little salt and oil, what is this?
There are three main elements of corn that have to come together to produce popcorn kernels that are good for popping. Those three elements are the percentage of water content; hard, undamaged, water impermeable shell; and a starchy center. When the kernels are heated up, the water inside begins to steam. Assuming the water impermeable shell doesn't have any cracks in it to let the steam escape, this creates a simple little steam/pressure cooker. The starch inside the kernel then turns into a kind gel-like substance as a result of this. Eventually, the pressure than pressing them out, and gives swiss cheese its dinstictive holes.
