Good for quiche and such.
1 ½ C all-purpose flour
Large pinch of sea salt
2 tbsp chilled or frozen margarine
2 tbsp chilled or frozen shortening
5-6 tbsp chilled water
This can be made in the food processor or a bowl. Sift the flour and salt into a large mixing bowl, or food process-pulse it a few times.
Add the fats in small chunks to the flour. Use either a pastry knife, or the blades of the food processor, to cut in the fats until it resembles course crumbs.
Add the water by the tablespoonful until the pastry dough begins to hold together. Gather it into a ball. Wrap in plastic wrap and place in the fridge for about 45 minutes before using.
