Has this ever happened to you? You're whipping cream and it's looking beautiful--soft, billowy peaks, almost perfect. Another second, and it's completely overwhipped: stiff and grainy. But you don't have to throw it out and start over.
To rescue overwhipped cream, you just add a few tablespoons of fresh cream and whisk it in by hand. As long as the overwhipped cream hasn't started to form clumps of butter, this will smooth out everything in just a few seconds.
And be sure to whisk it in by hand, so you don't overdo it yet again.
