Based on a formula I found in Denmark and NOT sold in the United States, my wood butter has 3 food grade ingredients: food grade mineral oil, bees wax, and carnauba wax. The bees wax by itself is too soft and the carnauba wax by itself is too hard. Mixed in the proper ratio the recipe makes an excellent wood rejuvenator. It is great for cutting boards and furniture. It comes in a 6 oz tin.
