My suggestion is to just go from left to right, top to bottom in each cupboard and drawer in your kitchen. Once you discard, you can clearly see what you have left. Make sure to do this same thing for your junk drawer. In Japan, I don’t think they have “junk drawers” and Mari (the author of The Life-Changing Magic of Tidying Up) would probably be appalled at the very idea. We are trying to get rid of junk, not find a special place for it.
Your next task will be to organize everything, grouping similar items together. When you organize these things, really commit to where you put them! This is where these items need to go every single time from now on! This is key to preventing your kitchen from descending into chaos!
My eleven-year-old daughter organized these cupboards for me. Look at how much room there is now! Do you see that abominable plastic container section in the top picture? Look how nicely she has organized it in the bottom picture. What is even more amazing (shocking, really) is that it has stayed looking like this for two weeks now. In the past, no matter how I tried to organize this thing, it became a booby-trapped kitchen hazard. The KonMari system really works!
