Paska is a traditional Easter bread that's butter and egg rich with a citrusy, lightly sweet flavor. It’s primarily associated with Ukrainian culture, although it's also found in Eastern Europe and countries with Eastern Orthodox populations. In Russia, the similar bread is known as kulich.If using paper Paska molds as I have, you may need to adjust your oven racks to accommodate the tall loaves. They will puff and rise tall in the oven as they bake.
