New York Style Pizza Sauce (Adapted from Serious Eats)

I adapted the recipe below from the Serious Eats New York Style Pizza Sauce recipe.

Ingredients:

1 (28-ounce) can whole peeled tomatoes

1 tablespoon extra-virgin olive oil

1 tablespoon unsalted butter

2 medium cloves garlic, chopped

1 teaspoon dried oregano

Kosher salt
1 medium yellow onion, peeled and split in half

1 teaspoon sugar*

Instructions:

Blend tomatoes in a blender until slightly chunky.  Set aside.

Combine butter and oil in medium saucepan and heat over medium-low heat until butter is melted. Add garlic, oregano, and large pinch salt and cook, stirring frequently, until fragrant but not browned, about 3 minutes. Add tomatoes, 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.


* I did not need the sugar in my sauce as the tomatoes were not that acidic but some tomatoes may need it.
