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 that have been cultivated for generations.
Unlike many paste tomato varieties, most strains of the called San Marzano heirloom are indeterminate.
This means they yield fruit throughout the entire summer rather than in concentrated two- or three-week periods like determinate varieties. This specific type of plum tomato has been selectively bred over time for packaging and long shelf life.
What Are San Marzano Tomatoes
Compared to Roma tomatoes, the San Marzano is thinner and much thicker with fewer seeds. It's also less acidic, which makes for a finely balanced and sweet taste.
"San Marzano" denotes a specific variety that is cultivated in a particular region of Italy, known as the Agro Sarnese Nocerino. This area is located in the valley of the Sarno River, close to Mount Vesuvius.
The volcanic soils in this region are believed to yield tomatoes that are sweeter and less acidic.
The Unique Taste Profile
The San Marzano variety is praised for its low acidity, sweet flavor, and fewer seeds. Their taste is often described as bittersweet – truly a whole new realm of flavor compared to the typical supermarket Roma.
The Minimally Processed Nature
San Marzano tomatoes, grown in the unique Sarno Valley in Italy, boast a flavor profile that sets them apart. They are carefully hand-picked and undergo minimal processing to preserve their natural taste and texture.
Their low water content makes them ideal for dishes that require a thick consistency, such as sauces and soups. The rich and sweet flavor enhances the taste of various culinary creations, including pasta sauces and pizzas.
Incorporating these tomatoes into your cooking recipes can elevate your dishes' overall quality and taste. Their distinct characteristics make them a sought-after ingredient among chefs and food enthusiasts alike.
Decoding the 'DOP' Label
'DOP' stands for 'Denominazione di Origine Protetta,' or 'Protected Designation of Origin.'
When you see a can labeled with 'DOP San Marzano,' it guarantees that the tomatoes inside are real San Marzanos, grown in Italy in the designated area, namely the San Marzano sul Sarno, an area of Italy between Naples and Salerno.
The Importance of DOP Certification
The DOP certification ensures the authenticity and quality of the product. It certifies that the tomatoes are true San Marzanos that have been grown and processed in the designated region in southern Italy.
This certification guarantees that consumers buy genuine San Marzanos only tomatoes, regarded as the best canned tomatoes in the world.
How to Guarantee Authenticity
Purchasing authentic DOP San Marzano tomatoes typically involves looking for the DOP label on the product. Beware of imitations or ones merely called authentic San Marzano tomatoes!
The indication "Pomodoro San Marzano dell'Agro Sarnese-Nocerino DOP" is a sign of genuine quality.
The Perfect Conditions in Campania, Near Naples
The growing conditions in the Campania Italy region are unique. The warm Mediterranean climate and rich soil from nearby Mount Vesuvius provide ideal conditions for the San Marzano tomato plant.
These near-perfect conditions result in a crop that is as close to tomato perfection as possible.
The Role of Rich Volcanic Soil
The volcanic soil in the Campania region is rich in minerals, giving these their unique and desirable taste. The minerals in the soil infuse the tomatoes with a unique sweetness and complexity not found in other tomato varieties.
The Challenge of Growing Outside Italy
While seeds are widely available, it can be challenging to grow these tomatoes outside Italy, particularly due to the specificity of their growing environment.
The warm climate, rich soil, and specific geography that contribute to the superior quality of Italian San Marzanos are difficult to replicate elsewhere.
The Process of Canning
These sold in cans usually come as whole peeled tomatoes. The canning process begins shortly after harvest, as the tomatoes are peeled and then canned in their own sauce to preserve maximum freshness and flavor.
Quality and Taste: Canned vs Fresh
Canned San Marzanos maintain their fresh flavor and high-quality taste, which is an excellent substitute when fresh isn't readily available. The canning process seals in the naturally sweet flavor, making them a fantastic choice for sauces and recipes where the flavor can truly shine.
Using Canned Tomatoes in Recipes
Canned San Marzano tomatoes are the secret ingredient used by many chefs worldwide. They can transform ordinary tomato sauce into a delightful culinary experience. A classic use is in Neapolitan pizza, a recipe where their rich, sweet, and tangy flavor adds depth to the overall dish.
