Black Bean Hummus

If you can't tell, Mr. Picky is on a black bean crusade right now. Don't know where he got this recipe but he's experimented with many different versions and likes this one the best.

1 clove garlic (smaller one)
1 can black beans (drain & reserve liquid)
2 tbs lemon juice
1 1/2 tbs tahini
3/4 tsp ground cumin
1/2 tsp salt
1/4 tsp cayenne pepper (or 1/2 tsp black pepper)
1/4 tsp paprika
olive oil

Put all in blender and blend. Accentuate with olive oil when serving.
