Soft Jam Buns

Warm the milk, melt the butter in it, then whisk in the egg, sugar, salt, and yeast until smooth. Gradually incorporate the sifted flour, kneading into a smooth, elastic dough.

Cover the dough with plastic wrap and let it rise in a warm spot for 1 hour until tripled in volume.

Divide the dough into equal portions and shape them into balls. Cover with plastic wrap and let rest for another 15 minutes.

Flatten each dough ball by hand, place the filling in the center, and carefully seal the edges to form neat round buns.

Place the buns on a baking sheet lined with parchment paper, cover with wrap again, and let them rest for another 15 minutes.

Whisk together the egg yolk and milk, then brush the mixture evenly over the top of each bun.
