Dissolve 1/4 cup slat in a gallon of cold water. Add the beans and soak overnight. Drain and rinse.
Combine soaked beans, pork parts, sausage, beef onion, pepper, scallion cilantro, tomato, and bay leaves in a large sauce pot.
Cover with water by 2 inches
Bring to a boil over high heat
Reduce to a simmer and cook adding water as necessary to keep the beans completely submerged until tender and liquid is a deep black. This takes about 6 to 8 hours.
Season with salt after tasting, the pork parts probably season it perfectly.
Serve with rice, greens, orange slices, hot sauce and farofa for a complete Brazilian authentic meal.
