Berliner

Mix flour, yeast, warm milk, egg yolks, butter, sugar, and salt into a soft enriched dough.

Knead until smooth, cover, and let rise until puffy and almost doubled.

Cut rounds from the dough, rest them briefly, then fry in moderate oil until evenly golden on both sides.

Drain well and pipe jam into the center of each doughnut.

Dust generously with powdered sugar and serve fresh.
