Tolosa Beans are famous because of the weekly market in the town of Tolosa, which has been held since 1,256 AD. Travelers from neighboring provinces had to pass through Tolosa on their way to France, so the reputation of the high-quality legumes spread. Tolosa beans can range from a dark purple to black. Until the second half of the 20th century, beans were a daily part of the Spanish diet. Industrialization and a rise in the standard of living resulted in a reduction in the amount of beans a typical Spanish family ate. Today, the Spanish diet is changing once again. Nutritionists are encouraging the consumption of beans as part of a healthy diet, and there is a renewed interest in traditional Spanish regional cuisines.
This recipe for Alubias Negras de Tolosa is a simple recipe, which can be made with any dried black bean available in local markets. After soaking, simmer in water, add Spanish chorizo and morcilla sausages and finally mix in sautéed onions, garlic, sweet pepper, and leek. It is a satisfying main course and a perfect dinner for cold weather.
