This creates a slightly sweet, intense tomato sauce typical of New York-style slices. It's also good served with pasta.
- 1 (28 ounce) can whole canned tomatoes
- 1 tablespoon extra-virgin olive oil
- 1 tablespoon unsalted butter
- 2 medium garlic cloves, grated on microplane grater (about 2 teaspoons)
- 1 teaspoon dried oregano
- 1 pinch red pepper flakes
- kosher salt
- 2 sprigs fresh basil, with leaves attached
- 1 medium yellow onion, peeled and chopped fine
- 1 teaspoon sugar
- Process tomatoes and their juice through food mill, pulse in food processor until pureed, or puree with hand blender. Puree should not be completely smooth, but should have no chunks larger than 1/16 of an inch. Set tomatoes aside.
- Combine butter and oil in medium saucepan and heat over medium-low heat until butter is melted. Add garlic, oregano, pepper flakes, and large pinch salt and cook, stirring frequently, until fragrant but not browned, about 3 minutes. Add tomatoes, basil sprigs, onion halves, and sugar. Bring to a simmer, reduce heat to lowest setting (bubbles should barely be breaking the surface), and cook, stirring occasionally, until reduced by 1/2, about 1 hour. Season to taste with salt. Allow to cool and store in covered container in the refrigerator for up to 2 weeks.
