They are all fabulous, with subtle changes yielding completely different results. None had meat, herbs, or spices. The butter and onion version that everyone thinks of as MH tomato sauce was tomato sauce III. Sauce I is the most strongly flavored. Simmer half a medium yellow onion (E: chopped) in a half cup olive oil just until soft. Don't heat the oil first! Stir in one finely chopped carrot and one finely choppen celery stalk. Add two cups canned pureed plum tomatoes, two treaaspoons salt, 1/4 teaspoon sugar, and simmer 45 minutes. Tomato Sauce II is fresher and more delicate. Roughly chop half a medium yellow onion, one small carrot, and one stalk celery. Simmer together with two cups canned plum toatoes with their juice, two teaspoons salt, and one quarter teaspoon sugar for 30 minutes. Puree everything, add 1/2 cup olive oil, and simmer another 15 minutes. Season to taste. Sauce III delivers that pure, sweet tomato taste. Simmer two cups canned pureed plum tomates, one stick* butter, one medium yellow onion peeled and cut in half, and 1/2 teaspoon salt for 45 minutes. Marcella said if you cook it too long you'll ruin the tomato. I can confirm. :( * later versions called for five tablespoons For any of the sauces you can use two pounds fresh plum tomatoes simmered until cooked through. Marcella rolls over in her grave when I do it but chiles and toasted spices are great additions. People have reported eating sauce II or III at room temp or straight from the fridge. https://www.thekitchn.com/marcella-hazans-amazing-4ingre-144538 Marcella Hazan's Amazing 4-Ingredient Tomato Sauce Ingredients 1 (28-ounce) can whole tomatoes, no salt or herbs added 5 tablespoons unsalted butter 1 small white onion, peeled and cut in half Kosher salt To serve: Cooked pasta Shaved Parmesan cheese Cooked pasta Place the tomatoes, butter, onion halves, and a pinch of salt in a large saucepan and bring to a simmer over medium-high heat.
