I bought this as a gift for my husband, who is an avid cook and baker. He'd been having a lot of success with his chocolate melt candy and handmade truffles so he wanted to take the next step.Every recipe he has tried has failed. The ganache recipe he tried first; it came out too runny. He tried the chocolate taffy one, and when he let it cool to the temperature specified for handling and stretching, it was already rock hard. The chocolate creme recipe came out brittle and chalky instead of smooth and creamy.He knows what he's doing and is extremely frustrated. He believes the recipes are wrong.I hope I can find a better cookbook for him.
