1. Dissolve the yeast in the lukewarm water. Add a teacup of flour and beat the mix. Cover the mix with a towel and place it in a warm place to rise. Slightly heat the milk, the sugar, the butter and the orange rind and place them in a bowl.
2. Add the yeast, the eggs, beaten, and the flour, stirring constantly. Make sure the dough is neither too soft nor too tough. Cover this dough with a towel and let it stand in a warm place for about an hour and a half.
3. When the dough has doubled in size, knead it again by hand and shape plaited breads. Brush the breads with 2-3 beaten egg yolks and bake them in a medium oven for about 30-35 minutes.
