I have a cook friend who uses a subset of the alchemical symbols for labeling in his home kitchen, which I've always thought was fun. Most of them aren't applicable but a lot of the kitchen basics have symbols: oil, salt, vinegar, sugar, baking soda a few others I'm forgetting.

"Most of them aren't applicable" - what, you mean you don't keep brimstone, cinnabar, and powdered silver in your spice cabinet?
