I am totally jealous of your pantry (I don't have one). That said, since I have limited space to stick pantry items, the two things I find helpful are (1) defining how much "stuff" we actually have space for – e.g. only 1 jar of ready-made sauce at a time and (2) containers to group small stuff together – e.g. our downstairs medicine station lives in a plastic fridge organizer from wally's. And I channel my inner retail clerk: neat orderly rows of like-stuff. Have fun purging!
Unfortunately, my apartment doesn't have a pantry, so I won't be of much help. I do love the amount of space you have to store things and I am really liking that shelving system for your spices. I do think you're off to a great start so I'm curious to see what you come up with.
I totally want to organize that. Badly. Does that make me weird?
