There’s nothing special about this recipe’s ingredients, but they all come together somehow to produce a lovely classic tomato soup. We’ve never tasted better.
Bring the tomatoes to a boil and simmer for 10 minutes. Mash the tomatoes with a potato masher.
Add the baking soda. Let the foam subside and add milk, salt, pepper, and butter.
Heat but do not boil, and serve immediately.
Optional: If you would like the soup to be thicker, add in a couple teaspoons—one at a time—of flour to the pot, whisking and tasting until you achieve the desired consistency.
