San Marzano Tomatoes Make a Best-Ever Vegan Soup

"You say tomato, I say tomato" say Ella Fitzgerald and Louis Armstrong in their classic song about lovers who can't even agree on how to pronounce everyday words like "tomato" and "potato." But today pronunciation isn't the only issue when it comes to "tomato."

Recently, I was brought up-close-and-personal with a controversy that is raging in the culinary world. 

When is a San Marzano tomato a real San Marzano tomato? 

Widely regarded as the best-of-the-best, low-acid San Marzano tomatoes are so prized they have been given a D.O.P. designation along with Italy's other prized food products like Basilico Genovese, Acute Balsamic di Reggio Emilia and Grand Padang cheese, to name a few. 

Officially the tomatoes are called Pomodoro San Marzano Dell'Agro Sarmese-Nocerino D.O.P.   "D.O.P" means "Denominazionedi Origins Protetta" or "Protected Designation of Origin." In the EU, if a can of tomatoes says "San Marzano," the D.O.P. seal must also be visible on the label to confirm that the tomatoes and sauce inside are guaranteed to have been grown in San Marzano and harvested and packaged according to the designation (more about that later).

That seems simple enough. If the label says "San Marzano," then it must be "San Marzano D.O.P." But not so fast. 

In the United States, "D.O.P." has no meaning. U.S. domestic producers can say "San Marzano" if the seeds are from that tomato strain. So it's buyer beware. If you want a San Marzano experience in the U.S., look for "D.O.P." 

Why are San Marzano tomatoes so highly regarded?

Grown within sight of Mount Vesuvius in the Agro Sarnese-Nocerino region near Naples, the tomatoes develop their delicate flavor, sweetness and low-acidity in the rich volcanic soil, under the ever-present southern Italian sun. To receive the D.O.P designation, the tomatoes must also be handpicked, steamed, peeled and combined with sauce made from San Marzano tomatoes. 

At the Wednesday Santa Monica Farmers Market, one enterprising farmer had identified his fresh tomatoes as "Sanmarzano." He might have found San Marzano seeds, but his Southern California tomatoes do not have the benefit of the Agro Sarnese-Nocerino terroir. 

The tomatoes are always packaged whole. If you see a label that says San Marzano "cherry tomatoes" or "diced tomatoes," that product might be of good quality but if you want a D.O.P. experience, look for that D.O.P. 

To purchase San Marzano D.O.P. products, search online. I found authentic products on Amazon, Supermarket Italy, Etaly and other online retailers and even many supermarkets like Ralph's and Von's as well as Italian shops and specialty food stores. Try Cost Plus World Market as well.

San Marzano Tomatoes-Garbanzo Bean and Vegetable Soup

I knew about San Marzano tomatoes but had never cooked with them because I have used my own roasted tomatoes and tomato sauce. When I was offered several cans of San Marzano tomatoes, I was very happy. I quickly made a favorite recipe, tomato-garbanzo bean and vegetables soup. The result was excellent. The tomatoes thickened the soup and added a layer of flavor that made me a fan.

Please try my recipe and track down authentic San Marzano tomatoes D.O.P. Enjoy!

Ugly Tomatoes Make Beautiful Meals

In the winter or spring farmers markets, you've passed them by with a disapproving look. Blemished fresh tomatoes. Discounted to a dollar or less, these unhappy looking suitors for your attention appear destined to become compost.

Occasionally you will see someone who has stopped at the bin looking through the misshapen mound and you probably think they are too poor to buy the perfectly red, perfectly shaped tomatoes grown in a hot house.

The truth is, there are treasures hidden there. Find tomatoes that are firm and only slightly blemished and you will have found diamonds in the rough. They lack summer's full-blasted brightness. but tomatoes grown during winter and spring's weaker sun grow thicker skins and develop a rich, deep umami flavor.

Oven roasted, these tomatoes find sweetness hidden deep within. The acid so prized in summer tomatoes is mellowed and sweetened in off-season farmers market tomatoes.

But treat these tomatoes with care. Brought home from the farmers market and left on the kitchen counter in the sun, they will quickly soften and turn bad. They are used to cold, so place them in the refrigerator and they will last days and even a week until you are ready to use them roasted as a side dish for braised meat, tossed with pasta, served on steamed rice or mixed into soups, stews and braises.

Roasted Winter/Spring Tomatoes

Check each tomato carefully. You want firm tomatoes. A few blemishes are ok because those can be easily removed with a sharp pairing knife. 

Heirloom tomatoes are especially flavorful.

Summer tomatoes can be roasted with a similar but different result. 

Serves 4

Time to prepare: 10 minutes

Time to cook: 30 minutes

Total time: 40 minutes

Ingredients

3 pounds tomatoes

1 medium yellow onion, washed, skins, root and stem ends removed and discarded

1 tablespoon olive oil

1/4 teaspoon sea salt

Freshly ground black pepper to taste

1 tablespoon Italian parsley, leaves only, washed, finely chopped

Directions

Preheat oven to 400F.

Prepare a baking tray with a small lip (about 1/2"). Lay a Silpat (non-stick silicone) sheet or a piece of parchment paper onto the bottom of the baking tray.

Using a sharp pairing knife, remove the stem and spot on the bottom where the blossom was attached. Remove any dark blemishes and discard.

Cut into 1" slabs. Place slabs onto the prepared baking tray.

Cut onion in half, cutting from top to bottom. Cut thin slices by cutting from top to bottom. Place in mixing bowl. Season with olive oil, sea salt and freshly ground black pepper. Mix with Italian parsley.

Spread onion-parsley mixture over tomatoes.

Place baking tray into oven.

After 15 minutes, using a spatula or flipper, turn the slabs over. Keep onion-parsley mixture on top to brown. Return to oven.

Remove after 15 minutes.

The onion-parsley mixture should have lightly browned. Carefully remove the slabs which are now very delicate from the pan. Reserve the onion-parsley mixture and all of the liquid that has accumulated in the pan. This is full of tomato-essence

flavor.

To use as a side-dish, reheat and serve in a bowl. The roasted tomatoes are delicious when added to soups, stews and braises.

If not used immediately, keep the roasted tomatoes in an air-tight container. They will keep in the refrigerator for several days or in the freezer for a month.
