Flaky Pie Crust

I got this from a pie class taught by Kim Morgan. The directions and measurements do need to be followed exactly.

2 c. flour
1/8 tsp. baking powder
1/2 tsp. salt
1 c. shortening
1/2 c. cold milk
1 Tbs. sugar

In a bowl, combine the flour, baking powder, salt and sugar. Cut in the shortening until mixture resembles small peas. Add cold milk and mix with a fork until dough follows fork around the bowl. The dough will be sticky, allow it to rest for 5 minutes. (Really, do this. I would be inclined to keep going. Why should dough get the chance to rest? I don't.) Roll on a floured board. Makes enough pastry for 2, 9" pie plates (with no crust on top) or 1 doubl crut pie (with crust on top.) Baking time depends on your filling. Check the filling recipe or cans for baking instructions.
