As the summer winds down and, with it, the fresh tomato season, you might wonder if there is a way to get that fresh tomato taste throughout the year. I wrote an earlier Cooking Tip on different canned tomato products but now I want to concentrate on Passata. It Italian, it is known as “passata di pomodoro”, meaning tomatoes passed through a sieve.
Passata is basically a thick but pourable uncooked tomato sauce. It is made from crushed and strained tomatoes to remove skin/seeds. Although some will say it is the same as tomato purée, it is not exactly the same product. Purée is the cooked version of tomato passata. Although the latter can be used in many dishes as a substitute for passata, it will not give you the freshness and brightness of a real passata. There are some brands that use both names on the jar.
What do you use it for? It is a great base for a pizza & pasta sauces, Indian dishes, soups, stews, chili, etc. It makes a thicker, more intensely flavored sauce than using the same amount of crushed or diced canned tomatoes.
Tomato passata may or may not be available in your local supermarket. It is certainly available online. If you find the product in the store, look at the ingredient list as it should only contain tomatoes and salt. It should be sold in bottles or small boxes, not cans.
There is no real substitute for passata but if your recipe calls for it and you have none, you can try a substitute. If the recipe only calls for a tablespoon or two, just try tomato paste. If you need more, put your canned tomatoes in a blender and then through a strainer.
You can also make it yourself at home and would be a great use for excess tomatoes from your garden. The best tomatoes to use are those that are ripe and flavorful, especially San Marzano and Roma. They should have a high flesh content compared to seeds.
There are a couple of different methods that people recommend. One has you boil the tomatoes briefly until they are soft and tender. After straining, they are put through a food mill. You can push them through a coarse strainer but it will be a lot more work depending on how many tomatoes you have.
An alternative method is to put chopped fresh tomatoes into a blender and process until there are no visible chunks. Pour through a strainer and push on the contents so only the skins remain. Discard skins.
No matter which method you use, do not add seasoning until you want to use it as it might limit the versatility. If you want it thicker, some recommend reducing it on the heat. However, this does reduce the fresh flavor and the same can be achieved when you actually use it.
For storage, you may either can it (using a proper canning method) or freeze. To freeze, pour into ice cube trays, freeze and then store in a freezer bag/container. Good for up to 3 months frozen. Canned passata may last up to a year in your pantry.
Do any of you have passata in your pantry? What do you use it for? Enjoy the fresh tomatoes while you can and if you have enough, try making passata for those cold, winter months!
