Great doctored baked bean recipe. Found this in an old hand-made school recipe booklet. Always requested at cookouts. Great the first day, better the second. Use only the molasses based beans not the ketchup style.
Brown beef with onions seasoned with salt and pepper until no longer pink. Drain. Mix in 2 cans of beans (undrained), sugar, vinegar and ketchup. Put in an ovenware dish, cover and bake for 1 hour at 350. I usually make this the day before and reheat to serve.
