“This is the traditional Romanian bread for different holidays, most prominently
Easter and Christmas. It is like a brioche or Portuguese sweet bread, but I think
better than either. It is slightly sweet and has a great soft texture. The fillings
are optional but add a lot of character. This recipe is based off of several online
recipes, some friends' recipes, and my own intuition. It comes out beautifully,
but is a labor of love! I'm sure there is a way to use a mixer or bread machine,
but I love doing this the old fashioned way. The preparation time includes
rising time.
