This one is for flavor
Salsa Huichol is one of the best Mexican hot sauces (technically it's a salsa picante) I've ever tasted. It has a deeper, smokier flavor than many others (think a really lively version of Cholula) and I find that it adds depth to just about any sauce, not to mention making home made burritos suddenly taste like they came from a taco truck and not my kitchen. This has really become my go-to sauce for south of the border flavors.
I saw somebody say it's not vinegar based, I don't want to argue with anyone but vinegar is clearly one of the four listed ingredients. Also any sauce like this is vinegar based, inasmuch as vinegar is what keeps the ingredients preserved.
Not offensively hot (probably okay to serve to company in most cases)
ConsFor some people, it will not be hot enough for what they are looking for. I have to stress that this is not intended to be an endorphin rush inducing sauce,but i highly recommend trying it if you you regularly use sauces like cholula or valentina in your cooking or for flavor. In fact, i would put the heat level dead in the middle between cholula and valentina.
