“Among the most inexpensive of foods, dried beans offer a bounty of fiber, iron, protein, folic acid and B vitamins. Black beans, also known as “turtle beans,” are an especially tasty variety, and make a lovely soup. Do not salt dried beans until they are cooked, as the salt slows down the softening process. On another note, so-called “cooking” wines or sherries contain lots of added salt. Do your palate and your body a favor and use a drinkable sherry in this recipe."
