How To make Cathe's Baked Beans

1/2 lb Bacon
3 md Onions, chopped
2 c Brown sugar
1/4 c Yellow mustard (prepared)
1/4 c Maple syrup
Campbell's pork/beans -(2 28-oz cans) Fry all but 3 strips of bacon until crispy. (Can do this in two batches in an 8-cup pyrex cup in the microwave. Try high setting for 4 minutes, stir bacon, and cook another 2 to 4 minutes or until done.) Remove to paper-towel covered plate and reserve. Crumble when cooled. Pour out all but 1/2" of bacon grease in the bottom of the cup. Stir in the chopped onion and saute until clear (but not brown), stirring every now and then. (Probably do this on high in batches of 2 minutes.) When onion is done, stir in the brown sugar and cook on high another minute or two, until the mixture is bubbly hot. Add mustard and maple syrup and stir to blend well. Combine beans, crumbled bacon, and sauce mixture in a large (9x14x2 inch) baking dish. Top with strips of raw bacon. Bake uncovered at 350 degrees F. for an hour or so, or until the bacon is done and the dish is bubbly and the liquid has cooked down some. Do not cook until dry. Serve hot or cold.
