Meanwhile, drain the tomatoes, place them in a food processor fitted with the steel blade, and pulse until they’re roughly chopped. With a slotted spoon, transfer the garlic to the food processor and pulse again to chop the garlic. Pour the tomato mixture into the pot with the olive oil, add the fennel, red pepper flakes, red wine, 1 tablespoon salt, and 1 teaspoon black pepper. Bring to a boil, lower the heat, and simmer for 30 minutes. Stir in the basil, taste for seasonings (it will be very spicy!), and keep warm over very low heat.
