I've gone down the vinegar route. Fire roasted green jalepenos, tomatilloes, & onions, plus garlic and lime juice. Peel, deseed, & blend it all up with just enough cider vinegar to get pH<4, boil for 15 mins or until consistency is reached, salt and pepper to taste, then transfer to clear glass Modelo bottles, crown cap loosely (dont crimp it hard) then boil as if canning, remove and hard crimp the caps. Keeps forever, and you simply have to pop the cap and jam in a plastic speed pourer...
Not the hottest, but its good for mild smokiness.
