I just purchased a large rectangular wooden bowl. It is made in Mexico and the woman (from a shop here in the U.S.) said that it was stained with coffee grounds and wax, but was definitely food safe. It has a very red color (not sure of the wood type) and as the woman suggested, I wiped it down with a damp paper towel when I got home. The towel came back covered in the reddish stain and it looks like it will continue to do so as long as I keep rubbing it! Is this a safe bowl for salads or is it just decorative?
