I'm sorry to say, but one of the best *fresh* salsa recipes out there is the roasted tomato slas recipe in "Everyday Mexican" by Rick Bayless.
I live in New Mexico, where proper, real salsa is a food group, and we get asked to bring this stuff wherever we go. Probably made 50 salsas before settling on this one.
Fire roast some tomatoes in your broiler (about 3 big tomatoes), and/or hit them with a blow torch and peel the skins (or buy one large can of fire roasted tomatoes at the store).
While you're doing that, put the jalapeno's and 4-5 pieces of garlic in a pan and start pan searing them.
About half a white onion, chopped (food processor works) finely --and put in a sieve and rinse.
Core and chop the couple of jalapeno's (the pointer ones are spicier, and leave in whatever amount of core/seeds you want to jack up the heat).
Put everything together in a blender, and do it up. Add cilantro to the end for taste, and you'll probably need some more garlic salt and maybe some onion salt...
Simple, fresh, good.
