When I lived in Knoxville, I used to buy Mrs. Bee's brand buttermilk biscuits. They were huge and tasted better than any I had ever had. They came from Bi Lo. Don't know who else might carry them. That brand, also, had a packaged dumpling that couldn't be beat. I had fish tonight.
FWIW. I like to use a prescription bottle, cut a hole in a hungry jack biscuit, fry it and put it in a paper bag full of confectionate, brown and pure sugar and shake it. Not a bad late night treat.
