Steps

1. 1

   Combine the warm milk, warm water, sugar, and instant yeast in a mixing bowl. Let the mixture stand for approximately 5 minutes to activate the yeast.

2. 2

   Add the egg white, the salt reserved for the dough, and the flour. Start with 4 cups of flour; add the remaining flour gradually as needed until a soft dough that is slightly sticky to the touch forms.

3. 3

   Add the butter and knead the dough for approximately 5 more minutes. The dough should become smooth and elastic.

4. 4

   Cover the dough and leave it to rise for approximately 1 hour, until it has visibly increased in volume.

5. 5

   For the caramelized onions, place the thinly sliced onions in a large pan with the olive oil. Cook over low heat until the onions begin to soften.

6. 6

   Add the salt and sugar to the onions. Cook, stirring occasionally, for approximately 15 minutes, until the onions deepen in color and become soft and caramelized.

7. 7

   For the meatballs, place the ground beef, salt, black pepper, and molasses in a bowl. Knead well until the ingredients are fully combined and the mixture holds together.

8. 8

   For the burger sauce, mix the mayonnaise, ketchup, mustard, and very finely chopped gherkin pickles in a bowl. Refrigerate until serving.

9. 9

   Pinch off mandarin-sized portions of the risen dough. Roll out each portion on a lightly floured work surface.

10. 10

    Place one portion of the meatball mixture, some caramelized onions, roasted pepper, and burger cheese in the center of each rolled-out piece of dough. Bring the edges together and seal them so that the filling is completely enclosed. As stated in the source, one hamburger may be prepared with two meatballs and the others with one meatball each.

11. 11

    Arrange the prepared stuffed hamburgers, seam-side down and spaced apart, on a baking tray lined with parchment paper.

12. 12

    Brush the tops with egg yolk and sprinkle with sesame seeds.

13. 13

    Preheat the oven to 180°C. Place the tray in the oven and bake the hamburgers for approximately 20–25 minutes, until golden brown on top.

14. 14

    Let the stuffed hamburgers rest for a few minutes after removing them from the oven. Serve hot with the burger sauce.

Notes

The meatball and filling quantities can be divided according to the approximately 8 servings specified in the source. The amount of flour for the dough is between 4 and 4.5 cups; adjust it according to the dough's consistency. The burger sauce is listed separately in the recipe, but the preparation section does not specify when to use it; serving it alongside the hamburgers is appropriate.
