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.

Please send me recipes and photographs when you make your delicious dishes using Pomodoro San Marzano Dell'Agro Sarmese-Nocerino D.O.P. and I will submit your recipe to enter a contest to win a gift basket of these wonderful D.O.P. San Marzano tomatoes.

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!

Preparing for Cold Weather with a Gathering of Summer Tomatoes

Time to post my suggestions about taking advantage of summer's bounty. 

Difficult to believe, summer is winding down. Even as the heat of the sun makes us wonder if summer will ever end, as the saying goes, "Winter is coming."

Walking through the farmers markets, I see a great abundance of tomatoes. With that abundance comes lower prices. Find a farmer who has too much of a good thing and the price comes down even more.

"Reduced to sell." "Soft ready to eat." Those are the tomatoes I look for. I'll buy them by the bagful. Five or ten pounds at a time. My plan is to prepare for a time when fresh tomatoes are a thing of the past.

I am anticipating a time when storm clouds are outside and I'm staring into the refrigerator looking for inspiration. I yearn for the produce of summer: leafy greens, corn and full-bodied tomatoes. But there is a way to enjoy the sweet-acidic deliciousness of tomatoes even in the darkest days of winter. Just look in your freezer.

With abundant tomatoes in the farmers markets, buy ripe tomatoes, roast and freeze them to be used in braises, soups and sauces in the fall and winter. Once blasted with heat in the oven, the tomatoes happily take to the freezer if they are covered in liquid.

Enjoy frozen roasted tomatoes whole or puree into sauce, and as rain beats against your windows and snow accumulates on your lawn, you will remember those heady summer flavors.

Oven-roasted tomatoes to use as a side dish or in sauces

Use ripe and over-ripe tomatoes. If you can find only unripe, hard tomatoes, leave them in a sunny spot on the kitchen counter until they ripen. Bruised tomatoes are OK as long as you use a sharp paring knife to remove the damaged parts. Avoid tomatoes with broken skin because of the risk of mold.

Any kind of tomato can be used: heirloom, Roma, cherry, large or small salad tomatoes.

A food mill is helpful when making the sauce. If one is not available, a fine meshed wire strainer will do almost as well.

When roasting the tomatoes, it is important to use parchment paper or a nonstick Silpat mat to prevent the tomatoes from sticking to the baking sheet. With a Silpat mat, none of the good bits and sweetly-delicious liquids that caramelize on the bottom are wasted.

Roasted Tomatoes

Tomatoes love the sun’s heat when they’re growing. And they love the oven’s heat that coaxes a rich umami sweetness out of their naturally acidic souls.

That sweetness is at the heart of the roasted tomatoes that will be in your freezer.

Prep time: 5 minutes

Roasting time: 60 minutes

Yield: 1 to 2 quarts

Ingredients

5 pounds tomatoes, washed, patted dry

1 tablespoon olive oil

¼ teaspoon sea salt

¼ teaspoon freshly ground black pepper

Directions 

1. Preheat oven to 350 F.

2. Line a large baking sheet with a Silpat mat or parchment paper cut to size. Use a baking sheet with a 1-inch lip to capture any liquids created during roasting.

3. Use a sharp paring knife to cut a “V” shape around the stem, remove and discard. With cherry tomatoes, any stems can be brushed off the surface without making a cut.

4. Place the de-stemmed tomatoes on the lined baking sheet, stem side up.

5. Drizzle with olive oil and season with sea salt and pepper.

6. Place in oven and roast 60 minutes.

7. Remove and let cool.

Freezing Whole Roasted Tomatoes

When you remove the baking sheet from the oven, you’ll notice a clear liquid has accumulated on the bottom. Some of that is olive oil. But most of the liquid is a clear tomato essence prized by chefs for its clean flavor.

If you are freezing some of the roasted tomatoes whole, use the clear liquid to cover the tomatoes in the deli containers.

Use airtight containers that are about the same width as the tomatoes so you will need a small amount of liquid to cover them.

Defrosting Whole Roasted Tomatoes

When you want to use the tomatoes, take them out of the freezer in the evening and let them defrost overnight. If any ice crystals have accumulated on top of the tomatoes, rinse off the ice before defrosting.

If you want to serve them whole, the tomatoes can be warmed in the oven or microwave. They are delicate, so handle them carefully.

Whole Roasted Tomato, Easy-to-Make Pasta Sauce

A deliciously simple pasta sauce to make any time of the year, not just in winter. Serve the pasta with steamed vegetables, a charred steak or a grilled chicken breast and you will have a perfect cold weather meal that warms body and soul.

The flavorful tomato sauce can become a vegan dish by simply omitting the butter and cheese.

Prep time: 5 minutes

Sauté time: 5 minutes

Pasta cooking time: 10 minutes

Total time: 10 minutes

Serves 4

Ingredients

1 tablespoon sea salt

1 pound fresh or packaged pasta

1 tablespoon olive oil

1 cup Italian parsley leaves, washed, roughly chopped (optional)

1 garlic clove, peeled, finely chopped

2 to 3 whole, large roasted tomatoes, skins removed

1 teaspoon sweet butter (optional)

Freshly ground black pepper to taste

1 cup freshly grated Parmesan or Romano cheese

Sea salt and freshly ground black pepper to taste

Directions

1. Place a large pot of water on high heat. Add 1 tablespoon sea salt to the water. Bring to a boil. Add the pasta. Stir well every 2 to 3 minutes.

2. Place a heat-proof cup in the sink next to a large strainer. When the pasta is al dente to your taste, about 10 minutes, pour the pasta into the strainer, capturing one cup of the salted pasta water. Reserve.

3. Toss the cooked pasta to prevent clumping.

4. At the same time the pasta is cooking, place a large sauté pan on a medium-high flame. Heat the olive oil.

5. Add the parsley and garlic. Lightly brown.

6. Holding the roasted tomatoes over the sauté pan, use your hands to tear them apart so you capture all the liquid. Add any liquid from the deli container.

7. Stir well and cook until the liquid is reduced by half.

8. Taste and salt, if needed; add a tablespoon or more of the pasta water.

9. Stir well and add butter. Taste and adjust seasoning by adding sea salt and black pepper.

10. When ready to serve, add the cooked pasta to the sauté pan. Over a medium flame, toss the pasta in the sauce to coat.

11. Serve hot with a bowl of Romano or Parmesan cheese.

Roasted Tomato Sauce

The tomatoes used to make the sauce are prepared and roasted in the same manner as those used to create whole roasted tomatoes.

Directions

1. Working with small batches, remove the roasted tomatoes from the baking sheet and put some of the roasted tomatoes into a food mill or fine mesh, wire strainer placed over a nonreactive bowl. Press the tomatoes through, collecting all the juice in the bowl.

2. Use a spatula to scrape off the pulp that will accumulate on the bottom of the food mill or the strainer. Add the pulp to the juice.

3. Discard the tomato skins. Or add to your compost. Or, even better, reserve in the freezer to use with other vegetable scraps to make vegetable stock.

Freezing Roasted Tomato Sauce

Put the open deli containers on a counter. Stir the tomato juice to mix with the pulp.

Fill each deli container to a half-inch below the top so that when the sauce freezes, the liquid will have room to expand and will not force open the lid.

When cooled, the filled containers can be placed in the freezer.

Defrosting Roasted Tomato Sauce

Even without defrosting, the frozen sauce can be used at the last minute, when you want to thicken a soup, add a layer of flavor to a braise or make a simple pasta sauce.

There are infinite ways to use this versatile sauce. One of my favorites is an easy-to-make pasta with sautéed vegetables.

If any ice crystals accumulate on the top of the sauce, rinse off the ice before defrosting.
