I often add prepared mustard to canned baked beans. This recipes calls for a few other ingredients, as well.
Here's the 1951 recipe for Tabasco Baked Beans.
1 1-lb. can baked beans
2 tbsp. pickle relish
1 tbsp. prepared mustard
1/4 tsp. Tabasco
4 slices of bacon
Mix beans with pickle relish, mustard and Tabasco in shallow baking dish. Top with bacon. Bake in moderate oven (350˚F) for 30 minutes. Serves 4.
