Sweet Blueberry Varenyky Filling

If using frozen berries, let them thaw completely. Drain any excess water - you don't want soggy varenyky.

Mix sugar and tapioca starch in small bowl until well combined. This will thicken the juices so they don't leak through your dough.

Place blueberries in large bowl and sprinkle sugar mixture over them. Toss gently with your hands - don't crush the berries.

Add lemon juice and mix once more. The filling is ready.

Place small spoonful of filling in center of each dough circle - about 1 teaspoon. Don't overfill or they will burst when you cook them. (Wet the edges of dough with water before sealing to help them stick)

Fold dough over filling and pinch edges firmly to seal. Make sure there are no air bubbles trapped inside.

Continue until all filling is used. Cook immediately in salted boiling water until they float, about 3-4 minutes.
