Periodic table of condiments
From Condiment No. 1 (Mayonnaise, which the table says goes bad in 3 months) to Condiment No. 75 (Maraschino, which apparently never goes bad), you can look up just about any condiment you can name to see when you need to toss it out. Or at least when these people think it goes bad.
Take it with a grain of salt (Condiment No. 2, it never goes bad!) though-it claims Lemon goes bad in 2 months. Stuff and nonsense. I've eaten 3 month old lemons that were perfectly good.
Mendeleev would be so proud...
