I buy Organic Cocoa Butter Wafers in bulk from Jedwards International, Inc. and repackage it into smaller containers.
The wafers make Cocoa Butter easy to store, weigh, and use. You can incorporate them in skin care products and/or candy - yes, they are food grade! (I've used them in both.)
From the Jedwards website: "Jedwards is proud to supply natural cocoa butter produced in a plant that is free of the 8 major allergens: Milk, Tree Nuts, Eggs, Wheat, Fish, Peanuts, Shellfish and Soybeans. Allergen statements are provided upon request."
