My second husband’s grandmother made pickled corn in big crocks. They sat in the kitchen with the cut up corn cobs (just cut in half length size)down in a vinegary, sour brine. She covered with a plate, brick and and tea towel to keep them submerged. My son loved these as a child. I couldn’t keep him out of there! Grandma loved to see him get in there though! Her name was Delsie and was really old time country – I loved her!
