I’d like spicy better if the burn didn’t linger. Wasabi, I love. It blasts through you, burning away all mucous in your sinuses and then it’s gone. A little dry mouth, so you need a bite of ginger and then another blast of wasabi.
I don’t have much tolerance for capsaicin, but I’m all about the isothiocyanate (the pungent compound in wasabi/horseradish/Chinese mustard/etc., and yes I had to look it up for this comment).
