Kifli (Hungarian Walnut Cookies)

Make dough:

In a large bowl, place the flour and the butter.

Using a pastry blender or two knives, cut the butter into the flour until the mixture resembles coarse crumbs.

Add the egg yolks and sour cream; stir with a fork until combined.

Turn the dough out onto a lightly floured board or pastry cloth. Knead the dough with your hands until it is smooth and can be shaped into a ball. If dough is too sticky, knead in more flour.

If desired, wrap dough in plastic wrap and refrigerate.

Make filling: In a medium-sized bowl, place the ground walnuts, granulated sugar, milk and almond extract.

Using a wooden spoon, stir in walnut mixture until ingredients are thoroughly combined.

Prehead oven to 400℉ (200℃).

Grease baking sheets with solid vegetable shortening.

To shape Kifli:

Divide the dough into quarters; wrap three of the quarters separately in plastic wrap and set aside.

On a lightly floured surface, roll out the remaining quarter of the dough to a 15 x 12 inch rectangle that is ⅛ inch thick.

Using a pastry wheel, cut the rectangle of dough into 3-inch squares.

Place a heaping teaspoon of the walnut filling in the center of each square; bring one corner of the dough over the filling to the opposite corner; pinch edges together.

Place Kifli on baking sheets; brush with the beaten egg.

Bake for 10 minutes or until cookies are golden brown. Remove from the baking sheet.

Fill the bottom of a pie plata with confectioners' sugar. Roll Kifli in the sugar.

Let cool on wire racks. Repeat steps with the remaining three quarters of dough.
