Preheat oven to 300˚F.

Strain the soaked beans and place them in a large heavy pot. Cover by 2 inches of cold water and bring to a boil, then simmer beans until they are tender. Skim any foam that rises to the top and discard. Drain the tender, cooked beans and reserve 1 cup of the cooking liquid.

Place the cooked beans and the 1 cup of reserved cooking liquid in a heavy 3 quart baking dish or pot, with a lid. I use a really heavy enameled cast-iron pan.

Add the thyme, orange zest, garlic, dry mustard, maple syrup and chicken stock to the beans. Arrange bacon over the beans; cover with lid and place in oven, bake for 1 hour. Remove the lid and bake for an additional 45 minutes.

Season with salt and serve from the baking dish (careful it's hot).
