Preparation

½ kg of dried beans (preferably multicolour and white, mixed)
A glass of barley
½-1 kg of fatty meat
An onion
Salt, pepper to taste
Oil (or lard)
The beans washed and soaked at least 12 hours before are placed in a large enough bowl, then add the well-washed barley, meat and pour over water, oil (or lard). Put the pot on low heat and let it boil until the beans soften, then put on top of the oil and put in the oven (also on low heat) for a few hours, until the beans (top layer) burn (dry). The top layer burns a little.
PS: if you have a healthy stomach in addition to the indicated meat, you can also add some smoked meat.
