Burned chocolate may be a disaster waiting to happen. However, there are ways to salvage it. In most cases, reheating it will restore it to its original taste. This method can be done in the microwave using low power and at about 40-45C. Make sure to cover the chocolate before heating. Otherwise, you will end up with a bitter product. Alternatively, you can chop it into small pieces and melt it over the stove.
You can eat burnt chocolate if the surface is still intact. However, it may look and feel unappetizing. You can temper it by adding a tablespoon or two of vegetable oil or melted vegetable shortening. Another option is to use a handheld immersion blender to smooth out the chocolate. If you can’t tolerate the burnt texture of the chocolate, it’s perfectly fine to save it for baking recipes.
A hot bowl of liquid can help revive melted chocolate. While this method is not the best option, it works. Adding some liquid will help dissolve the clumps and bring it back to its original fluidity. Try using only a teaspoon or so at a time. It works best for sauces or drizzles, but is not recommended for baking. It may get too hot and be difficult to eat, so make sure to keep this in mind.
A good way to salvage burned chocolate is to add some fat. When water is added to melted chocolate, it will seize and change its texture. It will also be grainy and unpleasant. Adding a bit of fat can help bring back the texture. Add the fat to the melted chocolate gradually, but only until it reaches the right consistency. If you don’t want to waste the chocolate, you can always use the melted chocolate in another recipe.
