I'm from the South and this is my grandmother's recipe for chess pie - very basic but very good. 9 inch pie crust 3 eggs 3/4 T white vinegar 1/2 c butter, melted 1 t vanilla 1 1/2 c sugar pinch of salt Preheat oven to 400. Prepare pie crust. Combine butter and sugar and simmer, stirring, for 5 minutes. Remove from heat and let cool just a little, stirring constantly. Add eggs, one at a time, beating well after each addition. Add vanilla, salt, and vinegar, and mix well. Pour filling into pie shell and bake for 15 minutes. Reduce heat to 350 and bake for 20 to 30 more minutes. Shake the pie gently; if the center just quivers slightly, it's done. Enjoy!
