There are people who like hot sauce and there are people who LOVE hot sauce. These people are influenced by the artisanal food movement—they're not the dudes chugging gallons of Frank's Red Hot (although, some of them USED to be those dudes), they're the ones who take their time perusing the condiments section of the grocery store, trying new bottles out each time. The idea of eating food without hot sauce is blasphemy to them.
If you have a hot sauce devotee in your life this Hot Sauce Tasting Kit ($32, 33 Books) is the perfect gift. The pocket journal allows them to obsessively catalog their adventures in hot sauce, and the gift set comes with two new bottles of hot sauce for them to try. Spicy!
