Hahaha. That whooosh up your nose is truly a unique feeling! You don't get that with hot sauce.
Since I live 20 minutes from the
Mustard Museum, and they're awesome people who have a HUGE cooler full of mustards to taste-test, I've had the pleasure of trying out the "hottest" mustard in the world.
Royal Bohemian Mustard is made with horseradish, so it gives the WHOOSH feeling up da nose. For my Wheel of Pain events, it's my favorite one to try, and to have others test, because the pain is very temporary.
I see they have another mustard, and the hottest horseradish. Guess another visit is in order.
