Ummmm no. It told me that I had nine of them just now. I went to put one on a plate and all nine vanished, replaced with my bow and arrows.
I had nine showing in inventory. I could equip it, but it did not show up as 'usable' until I was in a pk area (used a pk statue in my gh). Then when I went to use it (ONE press of the button, so obviously I didn't eat all nine) they vanished completely.

Please fix and reimburse. It looks cute and I enjoy collecting food items for display.
