Step 1. Mix the mash, which is cornmeal,sugar, yeast, and water---the following site shows you how to make the mash
Step 2. Put mash in a warm place for 3 to 4 days to ferment, producing the ethanol,
Step 3. Distill the mash, by boiling in a sealed pot, with copper tubing at the top. The gaseous ethanol rises through the copper tubing running through a bucket of cool water that cools the ethanol gas turning it into a liquid, ethanol.
Ethanol can be used for cooking. A simple stove can be made from soda cans.
