I thought of this while looking at the falling iguana's thread, and decided to give it its own thread.
Christmas night, my younger son's significant other made cayenne hot chocolate. She just threw some peppers into it as she was stirring, then took them out. Interesting stuff, when you took a sip, you got the chocolate, the cayenne didn't kick in for a second or so. After about half a cup I was ready to outside to cool off. I no longer drink alcohol, but I suspect that a shot of schnapps or something would really give it a kick. Or maybe induce spontaneous combustion.
