Ok, you made me look. Here’s what I have in my soup/seasonings Tupperware box, in decreasing expiration order:
Kroger Taco Seasoning (5/1/13)
Kroger Salad Magic Ranch Dressing Mix (2 pks, 1/6/10)
Kroger Salad Magic Zesty Italian Mix (4 pks, 1/3/08)
Kroger Sloppy Joe Mix (2 pks, 12/7/02)
…and 1 packet each of Hot&Sour Soup Mix and a Thai Peanut Dressing Mix both from DeMoulas Market Basket (no expiration dates) from when we lived in MA. Given that we moved to AZ in ‘99, these two have survived multiple moves. Guess I should use them first.
I’m like @Creekland. I pay no attention to expiration dates and just use my senses to determine if an item still passes muster. Because we are heavily vegetarian/pescatarian, the contents of the fridge/freezer rotate quickly, but some pantry items can be carbon dated, and I’m OK with that.
