Hot Sauce
Hot sauce is not just hot, but it is made from some pretty powerful ingredients, ones so strong, they create inhospitable environments for bacteria and foodborne illness. That is right, hot sauce is so cool (yes, pun intended) that it does not need to get stored in the fridge.
Hot sauce does have a longer shelf life if you keep it in the fridge and the flavor lasts longer. It depends on how frequently you use the hot sauce. If you are the kind of person who keeps the same bottle for years, you could be in store for some crusty hot sauce.
