I’ve never attempted to use canned tomatoes in the recipe, and can’t remember the last time I purchased store tomatoes, so I’m not sure how much liquid is in there in proportion to the fruit. My best guess to make this work would be to drain the tomatoes and then weigh them – but this would be a little high since the starting weight with raw tomatoes includes skins, seeds and excess juice that’s removed/drained off. Maybe around 16-80 pounds drained tomatoes? When I’ve drained my tomatoes after chopping, I end up with around 7 quarts in volume. There is no simple answer, unfortunately. If you give it a go, you may way to get pH strips to test the finished salsa and make sure the pH is below 4.6 for safe canning. If not, you could freeze, or add more vinegar.
I fell in love with Mexican food during a 2003 trip to California. Head over heels in love. I’m not talking your Chipotle Mexican Grill nonsense or your Taco Bell Tex Mex disgrace, I’m talking the sight and sounds of your host family’s Latin American sister-in-law chopping up wine-ripened tomatoes and fresh Jalapeños for Pico de Gallo on Thanksgiving. I’m talking pounding Coronas with Rudy all day and talking cultural differences, dreams and life in general. I’m talking the sound of Mariachi bands playing tableside in a side alley eatery near LA’s historic Olvera Street. The banging of pots from the stuffed taqueria kitchen. The smell of the spices hitting the heat of the stove… I love Mexican food. The authentic kind of Mexican food that few of us get to experience and shockingly many of us never knew existed… THIS, the authentic and the real, I love it!
