This is very easy to make. It is also a very smooth and beautiful dough.
In the book, there are directions for 3 different ways to make it: in a food processor, in an electric mixer and by hand. I did it in my food processor.
1 3/4 unsifted all-purpose flour (stir to aerate before measuring)
2 TBS. granulated sugar
1/4 tsp. salt
4 oz. (1 stick) unsalted butter, cold and firm, cut into small pieces
1 cold egg
1 TBS. ice water
|Fit the bowl with a metal blade. Put the flour, sugar, salt and butter in the bowl.|
|Pulse on and off for about 10 seconds until the mixture resembles coarse meal.|
|Place the egg and water in a small bowl and beat to mix.|
|Pour the egg and water mixture into the food tube slowly, processing about 20 seconds, until the mixture barely holds together.|
