The best canned tomatoes are the ones you’ve preserved yourself. But if you, like us, haven’t found the time or the stamina for that, don’t despair. The market is full of Italian canned tomatoes, but not every one of them deserves a place in your kitchen. At Spizing, we believe the sauce makes the dish, and the foundation of any great sauce is the quality of the tomatoes.
Here is how to navigate the labels and discover the “red gold”:
1. The Gold Standard: San Marzano PDO (DOP)
If you are looking for perfection, look for the San Marzano PDO label. These are tomatoes from the region near Naples, protected by European law as a product of controlled quality and origin.
- Why are they special? They are grown in the rich volcanic soils near Mount Vesuvius. They have a high sugar content, low acidity, and thick, dense flesh.
- No Chemicals: No preservatives, flavorings, or colorings are allowed in these cans. Only tomatoes and water.
- Important: If the label does not say PDO (DOP) and lacks a certification number, it isn’t authentic San Marzano, regardless of what the picture on the can suggests.
2. The Silver Medal: 100% Italian Tomatoes
The next level up are cans from reputable producers like Mutti, Chirio, or DeCecco, which explicitly state that they are produced in Italy from 100% Italian Tomatoes.
- Contents: You should see only two ingredients—tomatoes and water.
- Origin: Often, these are the San Marzano variety but grown outside the Naples region. The quality is excellent, but they lack the specific volcanic terroir.
3. The “Premium” Mass-Market Trap
In stores, you will often see Italian cans at high prices that list an “acidity regulator” in their ingredients alongside tomatoes and water.
Spizing Tip: If you are going to buy Italian tomatoes with additives, you are better off choosing a high-quality Bulgarian can. Often, our local tomatoes are of higher quality and come at a much better price than mass-market Italian imports.
4. Shape Matters: Whole, Peeled, or Unpeeled?
Forget about diced tomatoes. Always choose whole tomatoes.
- Whole and Unpeeled: These are the purest cans, guaranteed to have undergone no chemical processing for peeling. They are more expensive, but the taste is incomparable.
- Whole Peeled: The golden middle ground.
- Why avoid diced? Diced tomatoes are made from fruits that didn’t pass the selection to be kept whole—often because they were unripe or damaged. They always contain chemical additives for acidity correction.
Why is Acidity Your Enemy?
In Italian cuisine, balance is everything. If your tomatoes are too acidic, you will have to add sugar. However, too much sugar changes the profile of the dish and “masks” delicate and vital ingredients—such as the aroma of the guanciale in Pasta Amatriciana or the subtle note of a single garlic clove in an authentic classic tomato sauce.
The result? A dish that is merely “sweet and sour” instead of an explosion of Mediterranean flavors.
