Linzer Bars - cooking recipe

Ingredients

3/4 cup butter, softened
1/2 cup sugar
1 egg
1/2 teaspoon lemon zest
1/4 teaspoon salt
1/2 teaspoon ground cinnamon
1/8 teaspoon ground cloves
2 cups flour
1 cup walnuts, ground
1 cup apricots or 1 cup raspberry jam

Preparation

Preheat oven to 325\u00b0F Grease a 9x9\" square pan.
Cream together butter, sugar, egg, lemon zest, salt, cinnamon, and cloves in a bowl.
Mix in flour and walnuts.
Reserve 1/4 of the dough, and pat the remaining into the prepared pan, going up about 1/2 inch on each side.
Spread chosen jam flavor in a layer over top of the dough.
Flour a flat surface.
Use reserved dough to create a lattice top for the bars by dividing it into pencil-shaped strips and rolling it on the floured surface.
Arrange in a lattice pattern across the top of the jam, criss crossing the strips and pressing the ends against the dough on the sides of the pan.
Bake 45 mintures, or until lightly browned.
Cool in the pan on a wire rack before cutting into bars.
