Jacques Pépin makes buttermilk pancakes

"Very often, especially during the holidays, I buy cream—and very often I have cream left over. After a week or so I put that cream in the food processor and make butter—we can always use butter. And of course, with the butter you also get buttermilk. Occasionally I will use the buttermilk to make pancakes, which is easy to do. I serve them with whatever fruit I happen to have around."
