Since there are just the two of us, not counting our cats, it has often been the case that food we have stored in the refrigerator has gone over before we had the chance to use it.
Supermarkets often pack foods in quantities too large for two people to consume. Anything that is sold by the pound you should be able to downsize. Grapes are offered in large bags and most people feel they must buy the whole bag; we take a produce bag and select only enough grapes from the large store bag that we feel we will consume in a couple of days. I have no problem opening a store sealed package and selecting what we need, and it seems the stores have no problem with this.
Some things like broccoli, cauliflower and celery can’t practically be separated, but you can extend the refrigerator life by slicing off a thin layer of the stalk and covering the newly exposed area with a wet paper towel before returning it to the frig.
I have found I can extend the life of mixed greens, which are usually wet when I buy them, by placing a dry paper towel at the bottom of a storage container – putting in the greens – and placing a dry paper towel on top before sealing the container. I replace the towels if they are damp each time I use the greens.
The vacuum food saver we purchased last year has allowed us to buy meats in larger quantities without worrying about freezer burn. We also use the vacuum sealer to store blueberries, strawberries and any fruit that can be frozen before packaging. We even buy frozen fruits and store them in portion size bags for fruit desserts and smoothies.
Can anyone add to these ideas?
