I used dried corn shelled from the cob. Then roasted it in a heavy skillet or dutch oven (no oil) until look like fully roasted. Let it cool and grind it in coffee grinder, but at the same time I put the corn in the grinder I added some salt and some sugar. The final powder you can eat it straight or mixed with water or milk. The taste is delicious. You have to be careful when eating it straigt because it is so dry and can go thru the wind pipe and make you cough.
We used to do that when we were kids and we learned how to eat it without choking.
