In a large bowl, mix yeast, warm water, and sugar and set aside until frothy.
With a wooden spoon, stir in warm milk, eggs, egg yolks, butter, and orange zest.
Pour in 1/3 of the flour and mix. Add salt and mix again. Add a little flour at a time, stirring between each addition until all the flour is well incorporated.
Turn the dough onto a floured surface and knead until smooth.
Place the dough into a large bowl coated with oil and cover with a clean towel. Let sit 1 to 1 1/2hours or until it is doubled in size.
When the dough is ready, turn it onto a floured surface and cut into ten 2-ounce portions, and ten ½-ounce portions.
Roll each portion into a ball and place onto a lined baking sheet. Cover with a towel for 30 minutes.
Cut the smaller balls into stars, leaving the center attached.
Brush a small amount of water on the top of each roll to attach the star shaped portions.
Spread each star out to create bone shapes.
Brush each roll with egg wash and then bake for 18 minutes, or until golden brown.
While rolls are still warm, brush with melted butter and sprinkle with sugar.
