This traditional garlic soup from Castile may very well be what sustained Don Quixote in his windmill attacks. It is a simple soup and a type of gazpacho, in the sense that bread is used as a thickener. Spanish smoked paprika, or pimentón de la Vera—which comes in sweet, bittersweet or hot varieties, depending on your preference—is produced in a neighboring region and provides the distinguishing flavor to the soup.
