The end result: I've whittled own the number of recipes I have saved to a few favourites at I'll know I'll make again. And the box of assorted kitchen equipment got taken to a charity shop yesterday, without even glancing at what is still in it. I did cheat a little - there were a couple of things I took out for a recipe, but I hated the result, & will therefore never make it again, so using the item didn't count & it went back in the box.
Same with the microwave. Once in a while there's been something I've wanted to heat & being able to just stick it in the microwave would be convenient. But there's always been other ways, or I've decided it's not worth bothering.
There are one of two recipes left, so that part's not finished, but they don't require equipment I don't already have.
