I moved to Texas from Michigan some years ago, and really loved the hot sauce that comes with the tortilla chips at any Mexican restaurant down here. This is a take from a recipe a work-friend gave me. It's great, this is also what I use on my Cilantro Salmon. Recipe can also be easily doubled if you're having guests. Also, recipe is really to taste. Once you get to the last steps, use as much or as little cilantro, salt and lime juice as you like. If you prefer less garlic, use less.
