Homemade Spaghetti Sauce with Fresh Tomatoes

Squeeze out seeds from tomatoes; discard seeds. Grate the tomatoes on the large holes of box grater; discard skins. Transfer the pulp to a medium bowl. (You should have about 4 cups.)

Cook oil, garlic and crushed red pepper in a medium saucepan over medium heat, stirring often, until beginning to sizzle, about 2 minutes. Add the tomato pulp, tomato paste, sugar, salt and basil.

Increase heat to medium-high and bring to a boil. Reduce heat to medium and simmer, stirring occasionally, until reduced by half, 1 hour to 1 hour and 10 minutes. Discard the basil sprig. Serve immediately, or refrigerate in an airtight container for up to 1 week. The sauce may also be frozen for up to 6 months.
