Quince paste is known as membrillo in Spain. Quince, a relative of the apple, resembles a large, yellow, lumpy pear. Making quince preserves was one of the first uses of the pectin that occurs naturally in fruit. Quince paste tastes like a cross between apples and pears and is most often eaten with cheeses, but can be used like any other preserves. It offers a sweet contrast to the saltiness of traditional Spanish cheeses like Manchego and Cabrales. Cut a thin slice of the quince and place it directly on top of a thin slice of cheese and enjoy them together. You'll love the flavor explosion!
