Maraschino sauce has an infinite shelf life according to the Periodic Table of Condiments. I'm bothered that maraschino is red formeldahyde in disguise. Scary is the squeeze bottle of Hershey's Chocolate Syrup sitting in my refrigerator door for the past 3-4 years. 6-8 months, pshaw.
Cheese Whiz, Baco Bits, and Salt? Infinite.
Show me one person who finishes a bottle of ketchup in 5 months.
