Pattypan squash, also known as Spanish artichoke for its delicate taste, is a vegetable from the cucurbit family, with a flying saucer shape. Once neglected, this ancient vegetable is making a comeback in the market. Prepare the pattypan squash with this chorizo recipe to enhance its artichoke and hazelnut flavor. By simmering, the squash will absorb the spices from the chorizo. Potatoes will add a touch of sweetness.
