How to make
Clean, wash and soak the beans in cold water overnight.
The next morning, drain them, wash again and put in a pot on the stove with 1 tsp sugar. Let them reach boiling point and boil 30 min. on medium heat.
Remove from the stove, drain, rinse again and put them in a clay pot.
Chop the peppers, carrot and onions.
Add them to the clay pot with the beans, throw in all the spices and pour in the tomato paste after diluting it in a little water. Chop the ribs into pieces and add them too.
Pour in enough water or vegetable broth to cover them. Close with a lid and put in the oven.
Smother at 320°F (160 °C) for 3 hours.
