4 c. all-purpose flour, sifted
2 tsp. baking powder
1 tsp. salt
1/2 c. sugar
1/4 lb. butter
1 c. vegetable shortening
2 egg yolks
3/4 c. milk

FILLING:

1/2 c. seedless raisins
3 lbs. cooking apples, peeled and sliced
1/2 c. sugar
1 tsp. cinnamon
1 tbsp. lemon juice
Additional sugar-cinnamon mixture to taste

In a large mixing bowl, combine flour, baking powder, salt and sugar. Cut in butter and shortening as for pie dough. Mix in egg yolks, then milk. Divide dough in 2 parts.

On a lightly floured board, roll one part out as much as possible (dough will be very sticky), then place in an ungreased 12x18 inch pan and spread out with fingers to cover bottom and sides. Soak raisins in hot water until plump; drain and dry. Place raisins and apple slices over dough in pan. Sprinkle with mixture of 1/2 cup sugar and 1 teaspoon cinnamon, then with lemon juice.

Handle remaining half of dough similarly and lay over filling. Seal along sides. Sprinkle with additional sugar-cinnamon mixture. Cut into squares, then bake on lowest oven rack at 375 degrees for 1 hour. Yield: about 50 squares.
