I confess it is not my strong point, but I am beginning to improve! During the last Kitchen Cure I donated duplicates of a lot of kitchen utensils that I just didn't use. (They were initially given to me as gifts.)
This time around, my lone remaining slotted spoon has begun to rust rather badly; I just noticed it affecting the taste of food. So out it goes, and as a replacement, I bought a nice new slotted spoon at TJ Maxx.
Do you do this? One in, one out? Does it help you keep clutter in check? It's so easy to let "tool creep" happen — you pick up a new spoon here, a new skillet there (maybe as a gift) and you don't give away your old equipment. If your kitchen has reached a good equilibrium, with an adequate amount of tools for your everyday cooking, then this rule can be very helpful!
