If you’re a gardener, you likely end your season with a rack of green tomatoes and a quest to find a way to use them. Sorry, but this is not that recipe. I gave up on green tomato salsas several years ago—the vinegar required to make the salsa shelf stable when water-bath canning has always seemed overpowering.
Instead, I fell for the lovely green lanterns that grow into tomatillos, the traditional base for salsa verde. These little husked fruits clock in at pH 3.83, according to the U.S. Food and Drug Administration, well below the safe level for water-bath canning. The added acid covers the secondary low-acid vegetables and boosts the flavor. Even so, grilling and draining vegetables hasn’t been lab tested by National Center for Home Food Preservation, so I heavily researched and meticulously calculated the acidity for safe canning; to double-check my calculations, I test the recipes with a ThermoWorks high-accuracy pH meter. More details are in the Tips & Tricks for the recipe.
Tomatillos are as easy to grow as tomatoes; just be sure to buy two plants so that they cross-pollinate. Not surprisingly, I prefer them grilled like tomatoes—and have found yet another beverage use for their juice. Learn to make Grilled Tomatillo Salsa and Grilled Tomatillo Margaritas
