Tomato Sauce

This is a recipe from Biba's Taste of Italy, by Biba Caggiano. It is a delicious, light, and healthy sauce, and has a myriad of uses, from pasta to pizza. I have even used in soups. This is a tradional Italian staple, originally from the Tuscan region, and I find it nice to keep it on hand. If canning isn't your thing, it freezes very well.

Homemade Tomato Sauce
Conserva di Pomodoro

Ingredients
12 lbs. very ripe organic tomatoes, preferably plum tomatoes, cut into large chunks.
2 large organic onions, cut into pieces, coarsely chopped
3 organic carrots, cut into small rounds
3 organic celery stalks, cut into small pieces
1 cup loosely packed organic, flat-leaf italian parsely leaves
1 1/2 tsp. organic sea salt, or more to taste
small bunch of basil, stemmed (20-30 leaves)
1/4 cup organic, extra virgin olive oil

Directions
1. Combine the tomatoes, onions, carrots, celery, parsley, and salt in a large stockpot, over medium heat, and cook, stirring occasionally, until the tomatoes begin falling apart and the other vegetables are soft, 45 minutes to 1 hour.

2. Puree the tomato mixture in batches in a food processor fitted with the metal blade. Place a food mill with the disk with the smallest holes over a large bowl and pass the tomato puree through it to remove the seeds and skins. Return the sauce to the pot and season with salt. Cook it at a gentle boil until it has a medium-thick consistency. Stir in the basil and turn off the heat.
