You’d be surprised to learn what items in your pantry can last a lot longer than the printed expiration date! With proper storage, some food items can last for many years or indefinitely. In fact, one sticky sweetener has been known to stay edible for thousands of years.
HONEY
When stored in a sealed container and away from humidity, honey can be stored indefinitely. Honey keeps well because of its low water content. Archeologists have even discovered a jar of well-preserved, liquid honey in ancient Egyptian tombs over 3,300 years old. Over time, the consistency and color of honey can change. An easy fix for crystallized honey is to gently reheat it.
HARD LIQUOR
Unopened bottles of distilled spirits can last indefinitely with proper storage. Once opened and exposed to some air over time, pure base spirits like vodka, rum and whiskey will not go bad but may change in flavor. Liqueurs contain sugar and other ingredients that can spoil, so watch for signs of crystallization, discoloration or curdling. Cream liqueurs have dairy, cream or egg and only last about 18 months.
SALT
Keep salt in a tightly covered container to avoid moisture absorption, and it will last indefinitely. Since salt is a mineral, it cannot spoil.
RICE
Raw white rice keeps indefinitely with proper storage. Even polished white rice stored in oxygen-free and cold temperature conditions can stay fresh for up to 30 years! Brown rice, on the other hand, has a short shelf life of six to twelve months; its higher oil content causes it to go rancid more quickly. It’s best to keep rice in asealed, airtight container and store in a cool, dry place.

I open a ten year-old can of tuna and it was as tasty as the day it was purchased.
