The pierogi question — savoury or sweet?

Pierogi are not dumplings. They are a category of being. They can be savoury (potato cheese ruskie, sauerkraut mushroom, meat) or sweet (strawberry, cherry, blueberry). The savoury are dinner. The sweet are summer dessert. In our pierogi class held in the apartment of Pani Halina, who learned from her mother who learned from hers, the rule is simple: do not over-flour.
