I take a metal smithing class in school, and one of our projects is to make a utensil/holder/something to do with our favorite food. Mine is pie, so I’m making a pie/cake server. I’m making it out of copper, then sending it out to be silver plated when I’m done. I’d like to mount a stone or two in the handle, but still want to keep a magical touch to it.

My question is, are there any particular stones related to cooking and/or kitchen witchery?
