When Craig had his accident and almost 6 week hospital stay back in 2020, I had a good bit of time on my hands. Ended up going through and cleaning out the refrigerator, finding 2 or 3 open jars of the same thing, plus a few long expired items. Same thing with pantry. I organized the refrigerator by putting things like olives, pickles, relishes in the same area, then salad dressings, Asian items, etc. I yell at Craig now when he doesn't put something back in the correct place.
Got baskets for the refrigerator freezers. Chicken and seafood go in one. Beef and pork in another. All the various types of flours are in one. Frozen fruit, coconut in one. Etc, etc.
Pantry same thing. All the pastas are in 2 bins. Asian noodles and rice in one. Vinegars and oils together. Asian non-perishables in one. Unopened canned stuff in one. Baking items like baking soda/powder, extracts, food coloring in one. Chocolate in one. Etc, etc.
I actually know where things are now and don't have to hunt for stuff, and don't buy duplicates or triplicate.
And, I actually label things now with date and name. Because I've learned that I WON'T remember what it is.
