Also called gold string melon, spaghetti squash is unique among winter squashes; when cooked, the flesh falls away from the shell in strands like spaghetti, and retains a tender, yet al dente, texture. Savory flavor that is delicious, and low calorie, with a simple bit of butter and salt. Each plant can yield 5 to 7 squash.
