Cookbooks?

You could put in a decorative bottle of oil or something. If you're tidy, you could put a functional bottle of oil, but mine always get gunky and have to get hidden away, sitting in glass trays.

No hinges or holes anywhere? I can imagine a pullout for spices if there are holes inside...

Install a 'For emergency chocolate, Break glass' with a little hammer? Or put cookbooks in as a false front with your favorite treats in the back? Perhaps a tiny spring rod with a tiny curtain to an Elf on the Shelf home?

@Jen K - Such a cute idea! Definitely easier than searching for a cabinet door to match and fit there. thank you so much!

@Fori I like the idea of bottle of oil. Thank you!

There are no signs of hinges or holes anywhere on the frame or even inside the cabinet space. It's such a mystery!

you could make a couple of shelves in there for spices. Good place for them, right next to the stove.

@cat_ky - I like that too! I am going to try it out. Thank you!
