This is my friend, Nancy's, recipe & she got it from her friend, Mary. I don't care for buttermilk pie, but a lot of my friends & family LOVE it. And from what everyone tells me this is the BEST buttermilk pie they ever had. I've tried several different recipes & they are never as good as this one. It's really easy, just takes time in the oven to let the center set. FYI - a professional organization I was in used to have a bake sale every year & this was the most requested pie every year.
