TriniMike uses mustard in his one sauce which I have had and is pretty damn good.
How would we know what type of mustard is in this unknown hot sauce?
By the way try some mustard powder if you don't want to add extra vinegar and salt
Or make your own mustard and then use that for some real flavor. I made a 4:1 yellow:black mustard that I ground in a mortar and pestle and thinned with caribbean red, garlic, and cider vinegar puree and sweetened with thistle honey and it is absurdly good. My girl hates mustard and really dislikes spicy food and she even loved this mustard. I could only imagine a bbq sauce made with it, now my mind is working. I will be back with an update on the bbq sauce I make.
