Here's another great recipe from my friend Bonnie. It's really good.
AMISH BUTTERMILK PIE
1/2 cup melted butter
1 1/2 cup sugar
3 tblsp. flour
3 eggs, beaten
1 pinch salt
1 tsp. vanilla
1 cup buttermilk
1 deep dish pie shell
Heat oven to 400*F.
Beat sugar and butter together.
Add beaten eggs and vanilla.
Combine flour and salt.
Add buttermilk and flour mixture, alternating a little at a time until mixed.
Pour into pie shell and bake at 400*F for 10 minutes.
Reduce oven temperature to 350*F and bake from one hour to one hour and 20 minutes.
Pie should turn golden brown and stop jiggling when done.
