Serious Eats: Recipes
Note: Use only the ripest tomatoes. Don't use a bread that's too flavorful (no sourdough, for example) or rough. You want it to soften and blend into the soup completely. You can serve the soup as is with a drizzle of olive oil, sherry vinegar, and a sprinkle of chives and ground black pepper, or you can add a few diced vegetables back to the smooth base for texture.
