In a bowl, mix the flour, oil, butter, sugar, egg white, and salt. Gradually add water until you get a soft dough similar to donut dough.

Let the dough rest in a warm place while you prepare the filling.

After preparing the seasoned ground meat, flatten it on plastic wrap and cut it with a round cutter to get uniform sizes. Place them in the freezer briefly to firm up.

Meanwhile, cut small dough balls weighing about 1 ounce each (or larger if you prefer bigger burgers). Place them on a baking sheet, brush with egg yolk, sprinkle with some sesame seeds, and let them rise in a warm place.

Bake the dough balls in a preheated oven at medium heat until golden on the bottom, then turn on the top heat to brown the tops. Remove from the oven and let cool slightly.

Cook the ground meat on a grill, in the oven, or in a skillet with a little oil.

Cut the burger buns in half. Place the bottom half on a serving plate, add a little mayonnaise, a lettuce leaf, the cooked meat, and cover with a cheese square. Top with the other half of the bun. You can add tomatoes or onions if desired.

However, a tip for those preparing burgers for birthday parties or any occasion: do not add onions and tomatoes as the burgers will sit on the table for a while, and the taste of onions and tomatoes will change. Enjoy!
