Here’s the recipe I used for spare ribs – I started preparing about 11am to allow for time to marinate the ribs, and then allowing time to cook in the oven.
If you are intending to use dried beans, soak 1 cup in plenty of water overnight. Tip out the soak water. Put the beans into a saucepan with fresh water, and bring to the boil. Turn the heat down, and cook for 20 minutes or until cooked.
