Let's explore the essence of these majestic plum tomato fruits to understand what is special about San Marzano tomatoes that truly sets them apart.
The San Marzano is a specific variety of tomatoes, notable for its elongated, plum-like shape. This type of tomato, native to Italy, is actually considered an heirloom, a term used to describe plant varieties cultivated for generations.
