While San Marzano tomatoes are often referred to as a type of Roma tomato, this is not entirely accurate.

They are also relatively small and easy to crush by hand, which makes them a favorite among chefs and home cooks.
One of the main reasons why San Marzano tomatoes are so special is the unique combination of soil, climate, and culture in the Campania region of Italy, where they are grown.

That being said, you can still try growing San Marzano tomatoes at home, either from seed or from seedlings. Look for a reputable supplier that specializes in heirloom or Italian varieties, and make sure to provide your plants with plenty of sunlight, water, and nutrients. Keep in mind that the flavor and texture of your homegrown San Marzano tomatoes may not be exactly the same as those grown in Italy, but they can still be delicious and rewarding to grow.
Are all San Marzano tomatoes created equal?
No, not all San Marzano tomatoes are created equal. While the term “San Marzano” is protected by European Union law, which means that only tomatoes grown in a specific region of Italy can be labeled as such, there are still many different producers and suppliers of San Marzano tomatoes. Some of these producers may use more traditional techniques and higher-quality ingredients, while others may cut corners to save costs.
When shopping for San Marzano tomatoes, look for products that are labeled as “Denominazione d’Origine Protetta” (DOP) or “Protected Designation of Origin” (PDO). This label ensures that the tomatoes were grown and produced in accordance with traditional methods and standards, and that they meet certain criteria for quality and flavor.
