We are all very used to checking the expiration date on all of our foods. No one wants to get sick, waste money, or forget to use something that’s expiring very soon. There are plenty of foods, probably the majority, which you shouldn't eat after they've been around for a while, but there are a select few that will always be edible even after they've been around for years.
Honey: Your honey may look cloudy or crystallized but it is not spoiled so don’t throw it away! In fact, it never spoils if kept tightly sealed. If your honey does happen to be crystallized, heat it gently by running it under some hot water until it’s back to its original consistency. Then continue making your meals a little sweeter.
Rice: When kept free from contaminants, rice will never go bad. To keep it fresh make sure it’s kept in a cool, dry area and sealed in an airtight container. There is one exception though: brown rice, which can be stored for 1-2 years.
Sugar: Sugar is best stored in its original container in the pantry, white sugar in a dry environment and brown sugar in a moist environment. The shelf life of sugar is indefinite. So yes, that packet of sugar at the bottom of the bag you haven’t used since high school is still edible.
Liquor: Technically, liquor will never go “bad.” Unlike wine, unopened spirits don’t age in the bottle and will taste the same years later as the first day it was put in the bottle. However, an opened bottle of liquor can lose its flavor as time passes depending on its type, but it will always be consumable.
Vinegar: Commercially produced vinegar will likely outlast you! To properly store vinegar you should keep it in a cool, dark place and tightly cap it after each use. Don’t be too alarmed if your vinegar starts to change color or develop a smoky look after a while. If it has been stored properly, it should be safe to use.
Liquor will continue to age in the bottle. We know this from experience. My father-in-law used to get bottles of scotch and bourbon as Christmas gifts and he never opened them. They sat for 40 years in the same condition as when he received them. We opened some recently and the aging process was apparent. - fiamike
