National Hot Sauce Day is observed worldwide every January 22, celebrating the diverse varieties of hot sauce made primarily from chili peppers. The holiday likely originated from a hot sauce enthusiast wishing to honor their favorite condiment. Chili peppers, native to Central and South America, have been used globally since their introduction to Europe, Asia, and Africa in the 16th century. The first commercially available bottled hot sauces emerged in the early 19th century, with Tabasco being the oldest surviving brand, founded in 1868. On this day, enthusiasts can enjoy hot sauce with their meals, sample different varieties, or even create their own. A popular activity is the Hot Sauce Pain Challenge, where participants test their tolerance by sampling hot sauces of varying heat levels. Celebrators often share their experiences on social media using hashtags like #HotSauceDay and #NationalHotSauceDay.
