Banitsa (filo pastry coil filled with Bulgarian yogurt, cheese and egg)

Add the Bulgarian yogurt to a big bowl.

Break the cheese into the bowl.

Add the eggs and mix in (or whisk them first), then the baking soda.

Melt the butter in the microwave.

Line a baking sheet with parchment paper and butter the parchment.

Keep the filo under a damp cloth. Brush a filo sheet with butter, lay a second sheet on top and brush it too.

Spread a layer of filling over the sheets with an offset spatula, roll up tightly like a cigar, and coil onto the baking sheet; repeat, continuing the spiral.

Filo that has been frozen about a year falls apart when handled.

Brush butter over the top of the coil.

Bake at 400F for 45 to 50 minutes until golden brown on top, flaky and cooked through.
