This is hummus, only made with cannellini beans. You need the lemon, cayenne/harissa, and black pepper, or it will be bland and sludgy.
1 tin cannellini beans, drained and rinsed
1 clove garlic, crushed with a little salt
3dstsp tahini paste
Juice of 1 lemon
1tbsp plain yoghurt
Several pinches of cayenne pepper, or 1/4tsp harissa
1 1/2tbsp olive oil
Put all the ingredients except the oil in a food processor, and whizz. (You may not need more salt, because the beans have been preserved in briny liquid.)
Stir in the olive oil. In my view (as also stated in the entry on mayonnaise), the flavour of oil is damaged by the whizzing blade of a food processor.
