So I've packed it up in its box, & will leave it for a month or so. If I don't have any desperate urge to get it back out within that time, it goes.
That also made me realise how much kitchen utensils & bowls I have when I haven't bothered cooking owt from scratch in a few years. I just got out of the habit. I also have a bunch of recipes I've wanted to try that are cluttering up my notes app. So I've chucked all the stuff I don't use in a box, & I'm going to go through those untried recipes (as well as a bunch I've tried before). I'll make stuff & remove items from the box as I need stuff (though if I end up hating that particular recipe or see no reason to make it again, then the item will go back in the box). Anything left at the end goes. I've already made bread, & the large mixing bowl, loaf tin, & a wooden spoon have been deemed worthy of retrieval from Box Purgatory.
