In making "Mountain Dew" or "White Lightning'" the first step is to convert the starch of the grain into sugar. (Commercial distillers use malt.) This is done by "sprouting" the corn. Shelled, whole corn is covered with warm water in a container with a hole in the bottom. Place a hot cloth over it. Add warm water from time to time as it drains. Keep in a warm place for about 3 days or until corn has 2 inch sprouts. Dry it and grind it into meal. Make mush (or mash) with boiling water. Add rye mash that has been made the same way, if you have it. Yeast (1/2 pound per 50 gallons of mash) may be added to speed up the fermentation if you have it. Without it, 10 or more days will be required instead of about 4. In either case, it must be kept warm. When the mash gets through "working" or bubbling up and settles down, it is then ready to run. At this stage, the mash has been converted into carbonic acid and alcohol. It is called "wash" or beer and it is sour..
