"We had great success with your flint corn and look forward to the same this year. We were wondering does the corn need to be soaked in a lye solution before use (after harvesting and drying)."
A diet of only corn will lead to vitamin B deficiency and soaking in a lye solution makes the vitamin B available to the body. However as long as you have dry beans, meat, or any other source of vitamin B in your diet soaking in lye is not necessary.
