> Variation: for a stretchier sauce that’s good on pizza, add an extra 1 Tbsp. cornstarch. Instead of margarine, whip in 1/2 cup of oil after it cooks, and add as much as 1 cup of water at the end, or as needed to make a thick, smooth sauce that pours easily. Drizzle on pizza and for the last few minutes of baking, put pizza under broiler (watch closely!!) to form a stretchy, speckled skin.
