An update on what I've done so far.
I'm doing as much as I can to eat down the food that we have - one week, the grocery bill was a record low of $50 (usual is $150). I have consolidated roommate's food and glasses into on cabinet, and the same with my baking and Japanese food ingredients. I still have lots of extra kitchen stuff, but I now have the majority of the food actually in the kitchen. The pantry has 'doubles', hot chocolate, and the sweets that they want and I don't. It is also now holding a boxed set of china that had been in my clothes closet.I also went through my supplies of canning jars and reduced it to what I actually have room to store. This has been a big help.
Things that I have planned on going to DD when she moves out are being kept. She'll get some nicely seasoned cast iron skillets, probably some Corningware, some glasses, not sure what else. I don't mind keeping in a few extra years, and she'll get set up well from the get-go. Unlike me, using crap skillets because I couldn't afford anything else. There was a good reason I asked for Revere Ware pots for college graduation! I'm still using one that is going on 40 years old and good as new, from my mom's wedding gifts.
When the coffee pot died, I didn't replace it - I am actually fine drinking instant coffee, and no one locally has the kind of coffee machine I want. The additional space in the kitchen helped my organize the front closet, as stuff that was in there but belonged in the kitchen was able to put away correctly. Now that closet isn't overstuffed.
It's been nice to see the minimizing of the kitchen cascade into other areas of the house as well!
