This is the recipe used by Robyn Poarch, an Alabama girl now living in Los Angeles and making pies for the stars. Her clients include Courtney Cox, Ben Stiller, Laura Dern and Steven Spielberg. When asked to describe a buttermilk pie, she says it's kind of like a Southern creme brulee. The crust needs to be nice and cold going into the oven to make it work. The colder the crust the better.
