Lemon Buttermilk Sherbet

With the buttermilk leftover from the spice cakes, I got to make another recipe I've been hanging onto for a few weeks... Lemon Buttermilk Sherbet from David Lebovitz's last email newsletter. It's hard to make something bad with buttermilk. This was a lot easier than the ice cream I've made before; just mixing everything together and freezing in the machine. With ice cream, you have to cook a custard, usually with eggs. I like how you can see the little bits of lemon zest.
