MethodPut the Pinto beans in a bowl with water over night. The next day, boil them with the galic clove and laurel leaf for about an hour. Drain and retain the water. Peel and finely chop the onion and cut the bacon into strips. Brown the onion in a pan with a little oil. Then, add the bacon.
Add the peeled tomatoes with a little salt and mix. Then add the pinto beans. Peel the potatoes and cut them into cubes. Add them to the pan with some water and cook covered for 15 minutes.
After removing the garlic clove and the laurel leaf, bring the Pinto beans to the boil, add some salt and pour in the corn flour. Cook and mix with a whisk for about 40 minutes. Serve with Rosemary and Pepper.
