This recipe card has “Janet Boyd” in one corner. Not someone I remember, but I do remember Mom making baked beans.
Water for soaking beans
1 lb navy beans
1 cup milk
1 tbs dried mustard
1/2 cup brown sugar
1/2 cup molasses
Rind from 1/2 lb salt pork
Soak beans overnight.
Drain beans, add fresh water and boil until soft. (Time unspecified on card. Maybe 30 minutes?)
Preheat oven to 350F (the card just says “bake,” but this is a reasonable guess).
Drain most of the water from the beans and add everything else except the pork rind. Chop the pork rind into small pieces and parboil for 10 minutes. Add to the beans et al. Mix everything, put into casserole dish, and bake for two hours.
