Kolaczki are a traditional polish pastry cookie filled with jam/fruit filling. Since I learned to make them using pineapple filling, that's what this recipe uses too.

Ingredients
5 or 6 cups flour
1/2 teaspoon salt
3 tablespoons sugar
1 lb. shortening
1 pkg. active dry yeast
1 cup milk
1 teaspoon vanilla
3 egg yolks
1 can crushed pineapple (1 lb. 4 oz.)
1 cup sugar
3 tbls. corn starch

Instructions

Mix all dry ingredients and add shortening. Mix as for pie crust. Add egg yolks. Dissolve yeast in luke warm milk and then add to the mixture. Add vanilla. Let rise for a while.

FILLING: Bring crushed pineapple, cup of sugar, and corn starch to a boiling point in a large saucepan. Stir constantly and cook slowly for about 5 minutes. Cool for a few hours before using. Alternately, you could use prepared jams instead.

Roll out dough and cut into small squares (2 sq. in) and put filling in middle (about 1/2 tsp.) in each square. Bring corners of pastry together (to enclose the filling) and pinch the corners together. (You can either pinch two opposite corners and make a cannoli type shape or pinch all four corners to make a square.)

Bake in 350 degree oven for about 30 to 45 minutes. When done, sprinkle with confectioner's sugar. Serves about 50 people.
