I have two of those beetroot/pickle containers (the ones with the insert with which you lift to make it easier to access the beetroot etc) and some months ago I realised one of the inserts was missing.
Although he is not sure it was himself MOH has a habit of wrapping potato peelers etc in with the compost and out it goes. We are often fortunate in being able to find it before it actually goes into the compost heap but not always.
Getting back to the beetroot thingie....As yesterday was pretty warm (33C) I decided it would be good to have salad for a change and when I opened the tin of beetroot (have to admit I don't cook beetroot any more) and grabbed the first beetroot container of course it was the one without the insert. I mentioned this to MOH and he said "Oh I think I may have found it in the compost heap!"
This morning, after giving it a very good wash, he produced it and would you believe it, it is as good as new. I was amazed and realised just what a good product Tupperware really is. I have now washed the insert several times, scrubbed it with a toothbrush and know that it is really clean so now I have both containers back in service which really pleases me.
I don't buy Tupperware these days as I prefer the old style items they sold years ago and one downer is that I can't remove the lids of many of the modern containers. They are just too much for my arthritic fingers/hands to deal with but perhaps just as well as I doubt I could afford them.
Incidentally, that insert must have been in the compost for at least 4-5 months since we were last having salads on a regular basis which I think speaks wonders for their product.
