When I first tasted this wonderful, earthy soup, called potaje in Spanish, all I wanted was more. Chunky and substantial, it is a homely dish made from garbanzo beans, potatoes, and a little pork. The recipe below feeds a few, but you could make a big potful for a larger gathering. Like other stews, the flavor improves if made a day ahead. Serve with red wine, radishes, and coarse crusty bread. Flamenco music too, if possible.
