Add 2 drops of this to the sauce and let me know if you survive:
That is the scariest, hottest sauce on the damn planet. I put ONE drop into a pint bowl of homemade salsa and blew my lips off.
Ah, I know about The Source. That's mostly a collector sauce, doesn't taste good at all as it's just extract...lol
I did put in about a half a teaspoon of 10-Minute-Burn though...besides everything else in there.
