1 (28-ounce) can whole peeled tomatoes
1 tablespoon olive oil
1 tablespoon unsalted butter
2 medium cloves garlic, grated on microplane grater (about 2 teaspoons)
1/8 teaspoon dried oregano
pinch red pepper flakes
Kosher salt
2 (6-inch) sprigs fresh basil with leaves attached
1 medium yellow onion, peeled and split in half or ½ onion plus ? tsp of onion powder
1/2 teaspoon sugar
1.
Pulse tomatoes 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.
2.
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. Discard onions and basil stems. Season to taste with salt. Allow to cool and store in covered container in the refrigerator for up to 2 weeks.
This is my basic sauce. Now in the winter I use dried basil. In the summer I use fresh tomatoes from the garden and do a par boil/remove skin. I use this sauce for every thing calling for a red sauce.
Also I like powder cayenne pepper in place of red pepper flakes and omit the sugar. Tweek it to your liking.
