Varenyky z Syrom (вареники з сиром, curd dumplings)

The filling can be sweet or salty, but the seam has no patience for wet cheese. That is the whole lesson. Syr, our curd cheese, must be drained until it holds together in soft clumps, not slumps through your fingers, because once it weeps inside the dough the edge turns slippery and the dumpling starts telling on you.

These are the varenyky every Ukrainian child seems to meet first: pale half-moons or triangles, depending whose hands taught you, pinched at the table while flour gathers on your elbows and somebody puts another pot of water on because the first batch vanished. Salty ones get dill, black pepper, and smetana. Sweet ones take sugar and egg yolk, then butter in the bowl, sometimes sour cream, sometimes a spoon of jam if the day is feeling kind.

My hands remember the triangular fold from grandmother Vira, but don't let that bully you. A half-moon seals just as honestly. What matters is the dough rolled thin enough to show the shadow of your fingers, the filling kept dry, and the water held at a lively murmur, until the varenyky rise and the sound changes from heavy knocking to soft tapping against the pot.
