1 Bring the beans, water, oil, salt and garlic to boil in a wide bottom pot. Reduce the flame to medium and cook, covered, for 2 hours.2 Whisk the paprika, cayenne, cumin, lemon juice and a little water in a bowl to make sure you have no spice lumps, and throw the mixture in the pot. Cook 15 more minutes.3 You will find that the beans have almost completely dissolved all by themselves, but just in case you want a more elegant presentation, cream the soup with an immersion blender. Adjust the texture and seasonings. Makes a dozen ample servings.
