It is possible to make popcorn in a convection microwave by using a variety of methods. Add the pile of 20 regular, untreated, popcorn kernels into the pot and swirl it slightly to cover all the kernels with oil. But herein lies the other strange thing about popcorn - that 'popping' sound doesn't actually occur when the kernel explodes open to release the starch. This method uses hot air to cook the kernels, and is considered one of the healthier ways to prepare popcorn. As the popcorn is heated, the water turns into steam, which builds pressure inside the kernel. Similar phenomena occur when volcanoes or champagne corks pop.". Keep the last piles of kernels as they are. Eventually, usually at around 180C, the kernel's shell will crack, and the corn will pop. There are three methods of cooking popcorn: conduction, convection, and radiation. Anyway, once the pressure has been built to a critical point, the liquid starch bursts through the hull and cools down hyper-fast into a solid. Grains like sorghum, quinoa, millet, and amaranth all puff up in the heat of a stove. The expansion is caused by the kernels hard outer shell cracking open and allowing the steam inside to escape.
