?There is no one-size-fits-all answer to this question, as the best way to prepare brown beans will vary depending on the ingredients and methods used. However, some tips on how to make the perfect batch of brown beans include simmering the beans in water or broth until they are tender, adding seasonings such as salt, pepper, and garlic to taste, and using a variety of methods to cook the beans such as baking, boiling, or frying.
Proceed as follows:
Rinse the brown beans and soak them in cold water overnight.
Let them simmer, well covered by water (add some salt), until they are (very) soft. This normally takes 11/2 hours. Check now and then and add more water if required.
Add the syrup vinegar, then the potato flour suspended in a small quantity of cold water as a thickener.
Heat briefly.
