1/2       cup           whole milk 
1         9"            pie crust

Optional
May substitute 1 can of condensed milk for the sugar and whole milk. Also, sprinkle nutmeg to taste and color. My ma likes alot of nutmeg!

Preparation:

Clean, peel potatoes and slice potatoes. Boil until tender. Drain and mash potatoes. Add butter/margarine, spices, and sugar. Mix thoroughly and taste. Add eggs 1 at a time and mix thoroughly. Then add milk and mix thoroughly. Pour into pie crust. Bake at 375 degrees until center is firm. Should take about 35-45 minutes. At this point the pie is very tempting to eat so, let it sit for 15 minutes.
