I strongly suggest to make this sauce a day ahead and refrigerate as the flavors will blend together even more, and I advise that you double amounts if you are using it for enchiladas, what you do not use may be frozen for later use, this sauce freezes very well, in fact I most always make more to have handy in my freezer --- this makes a fantastic sauce for tacos or enchiladas it is the only one that I use I never purchase bottled this is much better --- the sour cream is only optional add in for a creamy-style sauce :)
