Dissolve the yeast in lukewarm water.

Add a teacup of flour to the yeast mixture and mix well. Cover and let rise in a warm place until doubled.

Gently heat the milk, sugar, butter, and orange rind in a saucepan until the butter is melted and the sugar is dissolved. Transfer to a bowl.

Add the yeast mixture and beaten eggs to the milk mixture, stirring constantly.

Gradually add the flour, stirring until a dough forms that is neither too soft nor too tough.

Cover the dough and let it rise in a warm place for about 1.5 hours, or until doubled in size.

Once the dough has doubled, knead it by hand.

Divide the dough into strands and braid them to form loaves.

(Optional) Press red-colored hard-boiled eggs into the braided bread before baking.

Brush the breads with 2-3 beaten egg yolks.

Bake in a medium oven (approximately 350°F or 175°C) for 30-35 minutes, or until golden brown.
