On the stove, cook at high heat about 1-2 hours or until beans are tender. Do not add any salt or anything containing salt until the beans are tender or they will remain a little crunchy. If using a slow-cooker, it may take longer to get them tender but you can do other things while waiting for them to cook.

Notes from Robert:
This is my favorite version of black bean soup. The orange juice and pulp really add a nice touch. As with any bean soup, a slow-cooker makes it a simple operation. This soup freezes wonderfully so make lots and freeze small containers for when cooking is difficult. Serve, perhaps with hot corn bread and a salad on the side.
