Tupperware Pie Crust

I choose to make the pies for Thanksgiving.  I decided to make my crust instead of taking the easier way out and buying crust.  Please note this recipe makes two pie crusts. 

2 c. flour
1/2 tsp. salt
1/2 tsp. baking powder
6 tbsp. cold water
3/4 c. shortening
2 tbsp. butter

Put in large Tupperware bowl, seal and burp. Shake until it forms a ball. Remove from container and roll.
