Paska and panettone are definitely similar since both are enriched breads baked to celebrate holidays. Though they both contain similar add-ins like raisins, candied fruit, and have a citrus flavour, they’re not the same. Panettone is Italian and is a Christmas specialty, while paska is Eastern European, with likely Ukrainian origins, and is made during Easter. The process for making panettone dough is also much longer since it starts with a “mother dough” (lievito madre), similar to sourdough.
