Growing up in Cincinnati, I used to joke that we'd never starve if there was a nuclear disaster, since we had such a massive stockpile of canned goods in the basement. (Talking to my friends, I think this is a generational thing).
But I notice that everyone has something that they can't live without a massive pile of.
For my dad, it's frozen chicken breasts and frozen chicken thighs. He loves to make stir fries and chicken curry.
For my fiance, it's jars and jars of spaghetti sauce. We can have 12 jars in the kitchen cupboard, and he'll buy a pack of three more as we're walking through Costco. Oh, and butter. He can't be without butter. I think there are five or six four-packs of butter (yes, REAL butter!) in the fridge at the moment. (His cholesterol is just fine, thank you very much, and he loves his toast slathered with real butter.)
At the moment, I stockpile tea - Lipton, and Red Rose tea. I make iced tea all summer long (with REAL sugar), so I bought a bunch when it was on sale. Fiance's reaction? "Why did you buy all that tea!?" However, he never complains that he has iced tea to drink. Nor me when I have plenty of chicken Parmesan with loads of red sauce to keep me happy.
What's multiplying in your cupboards?
