Ingredients
2 tablespoons unsalted butter
1 onion, coarsely chopped
1 to 2 cloves garlic (optional)
2 (14-ounce) cans whole peeled tomatoes
Coarse salt and freshly ground pepper
1 1/2 cups Basic Chicken Stock, or water
1/2 cup heavy cream (optional)
Preparation
Melt butter in a medium stockpot over medium heat. Cook onion and garlic (if using), stirring constantly, until soft and translucent, about 3 minutes.
Add tomatoes, their juices, and stock. Season with salt and pepper and bring to a boil, then reduce heat and simmer 10 minutes.
Working in batches, transfer tomato mixture to a blender, food processor, or food mill. Puree tomato mixture (if using a blender, cover the lid with a kitchen towel while machine is running).
Return soup to a clean pot and set over low heat. Whisk in cream, if desired; season with salt and pepper. Serve immediately or transfer soup to a bowl set over an ice-water bath to cool completely. Transfer cooled soup to an airtight container and refrigerate. Reheat over medium heat until heated through.
