Sweet Potato Pie 1/4 cup butter 1/2 cup brown sugar 1 1/2 cup mashed sweet potatoes 3 eggs slightly beated 1/3 cup corn syrup 1/3 cup milk 1/2 teaspoon salt 1 teaspoon vanilla 1 unbaked pie crust Preheat oven to 425F. Cream the butter and sugar. Add the potatoes and eggs. Mix well. Mix syrup, milk, salt, and vanilla. Ad the potato misture. Line a 9 inch pie pan with the pie crust. Put filling in pan and bake for 10 minutes. Reduce heat to 325F and bake for 35 - 45 minutes. I use light corn syrup and light brown sugar. I make my own pie crust but you don't have to. The recipe I use for pie crust is the recipe which I assume is still on the Crisco can. It takes a little more water than called for, though. If you make your own pie crust always use ice water which will make it more flaky. 1 pound of sweet potatoes boiled in their skins, then skins removed and the potatoes mashed will make just the right amount with a little bit left over.
