San Marzano tomatoes are a type of plum tomato known for their sweet flavor, low acidity, and firm texture. They are elongated in shape with a thick flesh and fewer seeds, making them ideal for sauces, canning, and roasting. Originating from the San Marzano region in Italy, these tomatoes are highly prized for their rich, complex flavor and are often considered the gold standard for making authentic Italian pasta sauces. Their vibrant red color and meaty texture make them a popular choice among chefs and home cooks alike for adding depth and sweetness to a variety of dishes.
