My grandmother had a bowl with the leftover biscuit mixture that had a towel over it and was kept under the sink. Not sure if she ever cleaned the bowl. She cooked fresh biscuits six days a week by 6am. Got sunday off when my grandad made pancakes. Boy how things change in two generations. Think she used animal lard also. Grandfather ate 4 biscuits a day and tons of bacon. Lived till 96.
