Ever needed a few ounces of unsweetened chocolate for a recipe, but find you don't have any on hand and don't want to go to the store? Or maybe you're trying to make a dairy free dessert, but can't find any unsweetened chocolate that isn't processed on equipment that also processes milk? If so, try making your own. It's simpler than it sounds, promise.
Just use this formula:
3 tablespoons cocoa + 1 tablespoon fat = 1 ounce of unsweetened chocolate
For the fat, you can use vegetable oil, shortening (melted), or butter (melted, preferably unsalted). Simply stir the cocoa and fat together and use as you normally would.
