Callos a la Madrileña

Description
Tripe is especially favored in Spain and, in fact, most countries where there is still a strong Spanish influence. This isn't surprising, because it makes a number of very different, but extremely tasty dishes. It requires long cooking times (less here because it is almost always cleaned and partially precooked when you buy it), but it keeps very well for days, in the refrigerator, and is even better when reheated than when first prepared. Since it's difficult to buy half a pig's foot or half a Veal knuckle, this recipe makes enough for 4 - 6 servings as a main course. Make a full recipe a day or two ahead of time, serve as many tapas as needed, then enjoy the rest as a main course or snacks. This can be reheated very nicely in the microwave, by the way.
 * Serves 4 – 6 as a main course, or makes 12 – 18 tapas
