1Combine flour and sugar into the bowl of an electric mixer. Cut butter into tablespoon pieces; add it to the flour and sugar. Use the paddle beater to cut the butter and flour together. Alternatively, this can be done by hand with a pastry blender
2With the mixer on low speed , or while stirring the mixture with a fork, pour in the cold water. When the dough starts to clump, and before it turns into a ball, stop stirring.
3Lightly knead dough in the bowl until it forms a ball. Divide dough into two parts. Flatten each part into a disk, and chill for about 30 minutes before rolling.
