Drain and rinse black beans and add to a high speed blender or food processor.
Add all other ingredients. (See instruction about plant milk below.)
Start with 2 T of plant milk and add more if necessary. If your hummus is especially thick and you need to add more than the 2-3 Tablespoons then add by teaspoon.
If you are using a high speed blender, you will probably need to stop part way through to scrape the batter down.
Serve with fruit, crackers, or cookies. Remember that this is very rich and a little goes a long ways.
