Step 1: Melt the butter in a wide soup pot over medium heat and let it brown for several minutes until it smells nutty.
Step 2: Add the sesame oil, then the onions, bay leaves, celery, garlic, thyme, chile flakes, smoked paprika, cumin and celery leaves.
Step 3: Cook stirring occasionally, until the onions have browned, about 20 minutes.
Step 4: Stir in the tomato paste, then add the beans (drain them first if you used soaked dried), 2 quarts water, and 1 tsp salt.
Step 5: Simmer, covered, until the beans are tender. Taste for salt and season with pepper.
Step 6: Cut the mustard greens off their stems and wash them. Simmer in salted water to cover until tender, a few minutes, then transfer to a strainer, rinse with cool water, and chop. Stir them into the beans.
Step 7: Taste once more for salt and season with plenty of pepper.
Step 8: Add a few spoonfuls of rice to each bowl and serve with Tabasco, Crystal, or other favorite hot sauce on the side.
