Aunt Hattie's Polish Raised Pineapple Squares, Mazurek

Aunt Hattie made a living out of baking this, and Placek, pound cake and other Polish recipes to order. That kept her pretty busy. A very old treasured family recipe. Jarred fruit filling (such as Solo brand) may be used instead of the home-made pineapple filling. Not quite as good though. And you might need more than one jar. Might as well bite the bullet and just make it yourself!

• Ready In: 1 hr
• Serves: 24

Ingredients

• 1  small fresh yeast cake (or 1 pkg. dry yeast)
• 1⁄2 cup  scalded milk, cooled
• 3  egg yolks
• 1⁄2 lb butter
• 3  cups  sifted flour
• 2  tablespoons sugar
• 1  teaspoon salt
• 1 (20 ounce) can crushed pineapple, undrained
• 1 -2  tablespoon cornstarch, just enough to thicken slightly

Directions

1. To start, make a pineapple filling by mixing a large can of crushed pineapple with cornstarch and simmering until thick. Might need a little fresh lemon juice to make tastier. Cool.
2. Mix together and set aside yeast, milk, egg yolks; this is the sponge. If using dry yeast, dissolve it in a little water first.
3. Mix as for pie crust: butter, flour, sugar, salt
4. Mix with the sponge.
5. Divide dough in half. Roll out half of the dough and line a 15 x 11 jellyroll pan.
6. Cover with the pineapple filling. Yes, it's a pretty thin layer. Supposed to be!
7. Roll second half, cut in strips and lattice over top
8. Let raise 1 hour. Bake at 350 for 35 minutes.
9. Drizzle with following frosting and sprinkle with chopped nuts if desired.
10. Frosting: 1 T butter, /2 t vanilla, powdered sugar.
