We've done our fair share of hot sauce taste testing, but the third annual California Hot Sauce Expo is taking our taste buds to a whole new level. For two days, City National Grove of Anaheim will fill with pepper-hungry attendees boasting their ability to withstand even the spiciest offender. Will they make it through 40 hot sauce samples and multiple eating challenges (our favorite: The Guinness Book of Record Smoking Ed's Carolina Reaper Pepper Eating Challenge)? We'll find out. Just be glad that there's beer on hand (though milk wouldn't hurt, either).
