A Tuscan tomato and bread soup that earns its credentials, with ripe tomatoes slow-cooked until they collapse, thickened with a purée of crusty bread and olive oil. Serve warm or at room temperature with fresh basil.
Put 2 cups of the bread cubes in a blender or food processor along with ⅔ cup water, ¼ cup olive oil, 2 garlic cloves, peeled and smashed with blade of a knife, and ½ teaspoon salt. Blend to form a smooth paste.
Heat 2 tablespoons olive oil in a large pot and place over medium-low heat. Add 1 cup finely chopped onion and cook until onion is very soft, but not browned, 8-10 minutes.
Add 3 pounds fresh ripe tomatoes, peeled and chopped (about 4 cups) *see note below for how to peel, 2 teaspoons sugar, 1 teaspoon salt and black pepper to taste. Turn the heat to medium and bring to a simmer. Cover the pot and continue cooking the tomatoes until they become very soft, about 25 minutes. Using a wooden spoon, mash the tomatoes into a coarse puree.
Add the bread mixture to the tomatoes and stir. If the soup seems very thick, add a little bit more water to thin it out. The texture should be dense and creamy, but still spoonable. Cook for a few minutes, then remove from the heat.
Drizzle olive oil over the remaining bread cubes. Put them in a skillet over medium-high heat and toast until golden and crisp, stirring them around, for about 5 minutes.
Taste the soup and season with additional salt and pepper. Garnish with the toasted bread,basil leaves an a swirl of olive oil. Serve warm or at room temperature.

Notes
To peel tomatoes: Fill a 4 or 5 quart pot halfway with water and bring to a boil. Drop in the tomatoes and cook 2-3 minutes. Drain and rinse with cold water. Use a small sharp knife to slit the skins on the bottom of tomatoes, then slip off the skins. Roughly chop and transfer to a bowl, along with any juice they exude.
Peeling the tomatoes is mostly for looks and texture. Go ahead and skip the blanching step and peeling if you enjoy the texture of the whole tomato.
If you'd rather not haul out your blender or don't have one, you can combine the bread cubes, water, olive oil, garlic and salt in a large bowl and let sit for 30 minutes until the liquid is absorbed and the bread is soft. Mash with a wooden spoon or potato masher — it doesn't need to be absolutely smooth.
Storing leftovers: The soup is best served fresh within 3 days. Keep refrigerated and warm gently in a saucepan to reheat.
