3 cups flour
½ cup finely ground almonds
1 ½ teaspoons baking powder
¼ teaspoon salt
½ cup sugar
Zest of 1 lemon
½ pound unsalted margarine or butter
2 tablespoons cold water
1 tablespoon lemon juice
1 egg white, lightly beaten
Preheat the oven to 350 degrees.
In a large bowl of an electric mixer, combine the flour, almonds, baking powder, salt, sugar, and lemon zest. Blend or cut in the butter until the mixture resembles very fine crumbs.
In a small bow, beat the egg, water and lemon juice until well blended. Add to the flour mixture and beat until completely blended and the mixture begin to form a dough. Do not over mix.
Transfer to a floured board and knead the dough into a ball. Divide the ball into 6 equal portions for easier handling. Flatten each portion with the palms of your hands and roll it out to ¼ inch thick. With a scalloped cookie cutter or the top of a water glass, cut into 3 ½ inch rounds. Place 1 heaping teaspoon of filling in the center of each round. Fold the edges of the dough toward the center to form a triangle, leaving a bit of the filling visible in the center. Pinch the edges to seal them.
Place the hamantashen on a lightly greased foil-lined baking sheet and brush with egg white. Bake fro 20 minutes or until lightly browned. Cool and eat.
