Preheat the broiler. Put the quartered tomatoes, sliced onion, and whole garlic cloves onto a roasting tray, spreading out evenly. Drizzle with plenty of olive oil and season well with salt and pepper and sprinkle with cilantro sprigs. Broil until everything is nicely charred, about 10 minutes (you want lots of deep rich color so don't be afraid if some of the edges get pretty black).
One thing though, I have never heard of simmering it. I switch up making mine to where I add all ingredients into a food processor and process until well mixed and chopped and then serve, or I only place the tomatoes and spices in the food processor and process until well chopped and then add the finely chopped onions, jalapenos and cilantro and then mix manually until all is well mixed. This makes for a chunkier salsa, and again I serve immediately.
I made this and cut the recipe in half, I have a question about safety because I accidently added 2 tsp sugar instead of 1.5 tsp ( half of 1 Tbls) I also added a bit more white vinegar and then 1/4 tsp cumin and 1/8 cup fresh lime juice. I didn’t peel the tomaties or get rid of the seeds and now I’m concerned I will die of botulism ….. I’m new to this so should I toss them or will it be ok?
Hi Lisa, yes, all the sources I’ve read say that bottled lime juice can be substituted for vinegar. Bottled is the key, not freshly squeezed. And adding some roasted green pepper should be perfectly fine as well. But if you have any doubt you can always buy some pH test strips (you can find them online, like on Amazon) to make sure the acidity level is correct.
