Directions

1. In a large bowl, dissolve yeast in warm water. Add 1 cup of flour, butter and egg, beat on medium speed until smooth. Add milk, sugar, salt and enough remaining flour to form a soft dough.
2. Turn dough onto a floured surface; knead until smooth and elastic, 6-8 minutes. Place in a greased bowl, turning once to grease the top. Cover and let rise in a warm place until doubled, about 1 hour.
3. Punch down dough. Turn onto a lightly floured surface; divide in half. Roll each portion into a 10x12-in. rectangle. Brush dough with melted butter. Spread each with half of the ham, raisins and olives to within 1 in. of edges. Roll up jelly-roll style, starting with a long side; pinch seam to seal.
4. Transfer to a parchment-lined baking sheet, seam side down. Cover with a kitchen towel; let rise in a warm place until doubled, about 1 hour.
5. Preheat oven to 350°. In a small bowl, whisk egg yolk and sugar. Brush over loaves. Bake until golden brown and puffed?, 30-35 minutes. Cool slightly, slice and serve.
