Whipped chocolate frosting from ganache
A reader wanted to know how to make this. She saw it on a cooking show. Here’s how I do it:
Bring a cup of whipping cream to a boil. Pour over 8 oz of chopped chocolate, (good quality chocolate bars, not morsels) cover and let sit 5 minutes. Whisk until smooth and refrigerate until slightly firm, about 1 hour but still spreadable. This is called ganache and it’s spread over cake. To make whipped frosting, cool ganache until firm, then beat with mixer until fluffy. Don’t overbeat as it may curdle.
