Alan's Pie Pastry

Ingredients

• 3 1/4 cups flour
• 1 tablespoon sugar
• 1/2 tablespoon kosher salt
• 1/2 teaspoon baking powder
• 1 3/4 cups cold unsalted butter
• 2/3 cup ice cold water
• 2 tablespoons sour cream
• 1 teaspoon vinegar

Directions

1. In a very large bowl, combine flour, sugar, kosher salt and baking powder.
2. With a pastry blender or food processor, cut in the cold butter, leaving chunks the size of peas.
3. Combine the ice cold water, sour cream and vinegar.
4. Add the liquid all at once to the flour mixture. Quickly stir to distribute; do not over mix. The dough should be slightly crumbly.
5. Let rest in the refrigerator for at least 2 hours or overnight. The finished dough should break, not stretch.
6. Divide into three portions and shape into disks. Use at once, or wrap and refrigerate up to 3 days, or freeze up to 1 month. Thaw overnight in the refrigerator if frozen.
