These plum tomatoes, like the name suggests, originated in San Marzano, Italy, and are famed the world round and favored by chefs and home cooks alike. This is because these tomatoes are longer than your typical plum tomato, while also having fewer seeds, meaning they have more flesh to work with, making them perfect for making your own sauces or roasting on pizzas. These tomatoes are also said to taste superior to others, with the perfect tomatoey intensity balanced by the right amount of sweetness and acid that will make your sauce sing.
