To prepare the tomatoes for blanching, cut a small and shallow X in the bottom of each one.

Fill a large pot with water and bring it to a boil over medium-high heat. Fill a large bowl with equal amounts of ice and water. When the water is boiling, boil the tomatoes in batches of four or five. Leave each batch in for 45 seconds to a minute, until the skin begins to split. Remove the tomatoes with the slotted spoon and drop them immediately into the ice bath. After about 30 seconds, remove the tomatoes from the ice bath with the slotted spoon and transfer them to a mixing bowl. Repeat until you have blanched all the tomatoes.

Pulse the tomatoes a few times until you achieve the desired consistency for your sauce. You can leave the sauce chunky, or continue pureeing until it’s smooth.

If you like to seed your tomatoes to try to get a smoother sauce, now is the time.

While the sauce is simmering, you can also add a few other ingredients for flavor, such as a few cloves of minced garlic, a bay leaf, or a couple sprigs of fresh basil or oregano.

Leave the tomatoes in the cold water for 30 seconds to a minute. This will stop the cooking process immediately and cool the tomatoes. Blanching makes it easier to peel fruits and vegetables.

With the remaining two tomatoes, chop them roughly into small chunks.

You can substitute any or all of the green pepper for red, yellow, or orange pepper. You can also add five to 10 chopped mushrooms to the sauce, a chopped zucchini, or a small head of broccoli, chopped.

The celery stalks don’t need to be chopped because you will remove them from the sauce before serving.

Stir in the tomato paste and continue simmering the sauce for another two hours. You don’t have to simmer the sauce for the full four hours, but cooking it for the full length of time will yield a thick, rich, and flavorful sauce. Cooking the sauce for one to two hours will result in a sauce that’s slightly runnier and not quite as rich.

Serve the sauce hot with pasta, rice, or vegetables.

Because pasta water has some leftover starch from the pasta, it will help to thicken the sauce.
