I used a mixture of olive oil, beeswax, and cocoa butter, because I don't keep walnut oil on hand and since I tend to cook for people with nut allergies, I'd rather play it safe. Googling indicated that beeswax and cocoa butter are suitable for
wood, and this was a mixture I had already made for skin care so it gets double duty! I heated it before using so that it was applied as a liquid. Also it smells so good because it has
rose oil in it. 🌹
