Heat it more briefly if you like your gags runny. Blend in short pulses until all ingredients are coarsely chopped. Taste and adjust proportions. Consider doing it twice. Certainly do this before touching any sensitive bits or mucous membranes.
Lime juice is the clear winner for the tartener.
Commercial green salsa is always unsweet and too salty for some reason. You can mix very hot peppers with very mild peppers to even out the flavors. I mixed a yellow bell and uncored jalape os for my last batch, and the color is really cool. Salt and lime juice to taste. More precisely, though, I find that when you get it wrong, its still pretty good.
