Polish Poppy Seed Loaves

Directions

1. In a small bowl, dissolve yeast in warm water. In a large bowl, combine the flour, sugar and salt; cut in butter until mixture resembles fine crumbs. Combine eggs, yolks and yeast mixture; add to crumb mixture and mix well. Beat in sour cream and vanilla until smooth.
2. Turn onto a floured surface; knead until smooth and elastic, about 6-8 minutes. Do not let rise. Divide in half. Roll out into two 12-in. squares; cover with plastic wrap.
3. In a small skillet, cook and stir poppy seeds and butter over medium heat for 3 minutes. Stir in the raisins, honey and lemon juice. Transfer to a bowl; cool for 10 minutes. Stir in candied orange peel and lemon zest.
4. In a small bowl, beat egg whites until foamy. Gradually beat in sugar, 1 tablespoon at a time, on high just until stiff peaks form and sugar is dissolved. Fold into poppy seed mixture. Spread over each square to within 1/2 in. of edges. Roll up each square jelly-roll style; pinch seams to seal.
5. Place on a greased baking sheet. Cover and let rise until nearly doubled, about 45 minutes.
6. Bake at 350° for 35-40 minutes or until golden brown. Remove from pan to a wire rack to cool completely. Combine icing ingredients; drizzle over cooled loaves.
