There’s something undeniably satisfying about preserving the flavors of summer, and few things capture the essence of ripe, sun-drenched tomatoes quite like Italian passata. A staple in Italian kitchens, passata is a smooth, rich tomato purée that forms the base of countless dishes—from simple pasta sauces to hearty stews. Whether you’re a seasoned canner or a curious beginner, making and canning your own passata is a rewarding process that allows you to enjoy the taste of peak-season tomatoes all year round. Let’s dive into the art of crafting this vibrant, versatile sauce.
What is Italian Passata?
Passata is an uncooked tomato purée that has been sieved to remove seeds and skin. Unlike tomato paste, which is thick and concentrated, or tomato sauce, which is often cooked and seasoned, passata is a blank canvas—pure, unadulterated tomato essence. This simplicity makes it incredibly versatile, allowing you to season it as you wish when you’re ready to use it.
Choosing the Right Tomatoes
The key to a great passata lies in the quality of the tomatoes. Opt for varieties that are naturally sweet, low in water content, and rich in flavor. The classic choice is the San Marzano tomato, known for its dense flesh and slightly tangy taste. However, Roma or plum tomatoes are excellent alternatives if you can’t find San Marzanos. Whichever variety you choose, make sure the tomatoes are ripe, firm, and free of blemishes.
Preparing the Tomatoes
Start by washing your tomatoes thoroughly under cool running water. Next, remove the stems and cut away any bruised or damaged areas. For ease of processing, cut the tomatoes into halves or quarters, depending on their size.
Cooking and Sieving
While traditional passata recipes don’t involve cooking, a brief simmer can make the sieving process easier and intensify the tomato flavor. Place your tomatoes in a large pot and cook them over medium heat for about 10-15 minutes, just until they start to break down and release their juices.
Once softened, pass the tomatoes through a food mill or a fine sieve. This step is crucial as it removes the seeds and skins, leaving you with a smooth, silky purée. If you prefer a more rustic texture, you can skip the sieving, but be mindful that this will affect the final consistency of your passata.
Warming jars and equipment
Before canning your passata, it’s essential to warm your jars and lids to prevent cracking. Wash the jars, lids, and any other equipment you’ll be using in hot, soapy water, then rinse them thoroughly. Submerge jars and lids in hot water for about 10 minutes before filling them with the tomato sauce.
Canning the Passata
With your jars warmed up and your passata ready, it’s time to start canning. Using a ladle and a funnel, pour the hot passata into the jars, leaving about ½ inch of headspace at the top.
Note: Since we are going to use water boil canning for this, we need to make sure that the acid level of the passata is high enough to be able to water bath. Add 1 table spoon of bottled lemon juice to each pint jar.
Wipe the rims clean with a damp cloth to ensure a good seal, then place the lids on top and screw the bands on until fingertip-tight.
Process the jars in a boiling water bath. Place the filled jars in a large pot of boiling water, ensuring they’re fully submerged, and process them for 35-40 minutes. The exact time will depend on your altitude, so be sure to adjust accordingly. I have written a whole blog post about it. You can read about that here.
Cooling and Storing
Once the processing time is up, carefully remove the jars from the water and place them on a towel-lined surface to cool. As they cool, you should hear the satisfying “pop” of the lids sealing. After 24 hours, check the seals by pressing down on the center of each lid—if it doesn’t move, you’ve got a good seal. If any lids didn’t seal properly, refrigerate those jars and use them within a week.
Store your sealed jars in a cool, dark place, and enjoy your homemade passata for up to a year. Once opened, refrigerate the jar and use the contents within a few days.
Enjoying Your Passata
Homemade passata is incredibly versatile and can be used in countless recipes. From a quick pasta sauce to the base for soups, stews, and braises, this preserved tomato purée is sure to become a kitchen staple. The best part?
