Now that I’ve grown San Marzano tomatoes, the challenge is what to do with them. I peeled and water bath canned the first couple of batches. That’s something: a lot of work for the yield. There have been fresh pasta sauces, salsa, and plain San Marzano tomato sauce. There is a lot to like about this variety of tomato and the exceptional flavor is just the beginning.
I didn’t know if my Iowa garden would grow Sam Marzanos as good as what is available from Italy in tin cans at local grocery stores. Canned tomatoes from the store are convenient. Mine are fresh and good enough to grow again next year. In our household, flavor wins over convenience almost every time.
I planted a row of twenty plants in ten cages on the west side of the tomato patch. It ensured there would be a substantial quantity and they would get adequate sunlight. That plan worked and there is lots of good-looking fruit through the season.
Where I landed for those not used fresh is straight forward: tomato sauce for canning or freezing.
My process to produce the sauce is one I developed over years. After washing and sorting the tomatoes, I core them, cut off bad spots and place them in a big stainless steel pan with a half cup of tomato juice or water. I bring them to a boil and then let them cook for two or three minutes until the skins are loosened. I turn off the burner and let them cool on the stove top for an hour or two.
Next, I scoop the parboiled tomatoes into my funnel and let them drain the tomato water. This takes an hour or so for most of it to seep out. Finally, I spoon the mixture into a blender and blend until as smooth as possible. Now we’re ready for use, canning or freezing.
A couple of notes:
No seasoning at this stage.
I no longer remove the skins in order to keep their nutritional value in the sauce. Blending chops the skins so they are hardly noticeable.
Well-ripened tomatoes produce the best flavor. If they come in from the garden and need ripening, it serves the goal of peak flavor to let them finish ripening on the counter.
The sauce is not really cooked. It is an ingredient for future dishes like pasta sauce and chili. San Marzanos benefit from a long, slow cooking process. That will come when I use the tomatoes in a dish.
Finally, I water bath can some jars of tomato sauce. In late summer an active kitchen garden is lacking refrigerator and freezer space. Having the tomato sauce in shelf-stable jars helps alleviate the space problem.
I will continue to process San Marzanos as a separate variety until they are gone. With the mix of canned wholes and sauce of this and other varieties we will be well on the way to year-round tomatoes in the kitchen.
It’s where we like to be.
