Rosca de Reyes
This traditional holiday Mexican bread is a bit time-consuming, but absolutely worth the effort.
Don't worry too much if you do not see much change in the dough, especially in cold climates.
You do not need to use all 3 egg whites to brush the dough. If your paste is too dry in step 6, you may add 1 teaspoon of egg white.
Use candied citrus peels in 2 or 3 different colors if available.
