Nuts: Almonds, walnuts, and pecans can last for years in airtight containers in a cool, dark place, thanks to their high-fat content, though they may eventually go rancid.
Chocolate: Properly stored chocolate can remain fresh for 2-4 years beyond its expiration date due to the resistance to spoilage from cocoa solids and fats.
Canned Vegetables: Canned vegetables can last for years beyond the "best by" date when stored in a cool, dry place, thanks to the preserving nature of the canning process.
White Flour: Stored in airtight containers in a cool, dry environment, white flour can last for years, lacking the oils found in whole grain flours that can go rancid.
Cornstarch: Used as a thickening agent, cornstarch can last indefinitely when stored in a cool, dry place and kept away from moisture.
Soy Sauce: With its high salt content and fermentation process, soy sauce can last a very long time, especially if unopened.
Honey: Due to its low moisture content and acidic pH, honey has an indefinite shelf life, demonstrated by pots found in ancient Egyptian tombs still perfectly edible after over 3,000 years.
