Have you been storing your soy sauce correctly? How about your peanut butter? Whether a condiment needs to be refrigerated or not can affect the taste, texture, and shelf life of the product. And, not everything that you open needs to take up valuable space in the fridge. For instance – olive oil tastes better at room temperature, so there's no need to refrigerate it. Salad dressings, on the other hand, often contain natural ingredients, so the bottles need to be refrigerated to prevent the product from spoiling. Same with soy sauce: the bottle tells you to refrigerate after opening. Peanut butter, depending on whether or not it's all-natural, can be stored on the shelf with no harmful after-effects. In fact, regular peanut butter can last about three months in the cupboard. Our friends at Real Simple are sharing which four condiments needs to be refrigerated and which five condiments are best at room temperature. Some of these may surprise you – have you been storing mustard correctly?
