Here's our fire grilled salsa recipe:
2 large cans of whole tomatoes drained (liquid reserved) or 3-5lbs peeled home grown tomotoes
1 small onion sliced into chunks
1 green bell pepper chunked
2-4 jalapeno peppers
2 clove garlic
2 limes (or a grapefruit)
1-2 small cans tomato sauce as needed and preferred
fresh cilantro
salt and pepper
Grill tomatoes, onion, and peppers over charcoal (much much better than gas grill)
In a food processor, process the tomatoes, onion, peppers, fresh garlic and juice of one lime (or grapefruit), and desired amount of cilantro (I'd go with about 1/4 of a bunch as I don't like too much cilantro myself).
Give it a taste and add more citrus, salt, pepper, cilantro as desired and tomato sauce as preferred.
I've never tried to can this but it stays good for several days. It's the best salsa we've ever made!! This is my dad's recipe except he doesn't do his fire roasted and it's very tasty his way as well.
