Trying the hidden burger everyone is talking about! ✨Recipe: Ingredients: Dough • 4 cups all-purpose flour • 1 cup lukewarm milk • ½ cup lukewarm water • 1 egg white • 5 g instant yeast • 1 tbsp granulated sugar • 2 tbsp butter, softened Burger Sauce • 4 tbsp mayonnaise • 2 tbsp ketchup • 1 tbsp mustard • 2 pickles, finely chopped Filling • 1 lb ground beef • 4 slices cheese • Pickles • Onions, sliced • Butter, for cooking • Salt and pepper, to taste For Topping • Egg wash • Sesame seeds Directions: 1. In a large bowl or stand mixer, combine the flour, lukewarm milk, water, egg white, instant yeast, sugar, and butter. Mix until a dough forms, then knead until smooth and elastic. 2. Transfer the dough to a lightly greased bowl, cover, and let rise in a warm place for about 1 hour, or until doubled in size. 3. In a small bowl, combine the mayonnaise, ketchup, mustard, and finely chopped pickles. Mix well and set the burger sauce aside. 4. Divide the ground beef into 4 patties and season with salt and pepper. Sear in a hot pan for about 1 minute per side, just until browned on the outside. Remove from the pan and set aside. 5. In the same pan, melt a little butter and add the sliced onions. Cook until soft and caramelized, then remove from the heat and set aside. 6. Divide the risen dough in half. Roll each half into a large circle about ¼ inch thick, then gently lay each piece into a bowl to help form the shape of the hidden burger. 7. In each dough-lined bowl, layer a slice of cheese, a burger patty, caramelized onions, burger sauce, a second burger patty, pickles, and another slice of cheese. 8. Pull the edges of the dough up and over the filling, then firmly pinch the seams together to completely seal everything inside. Carefully flip onto a parchment-lined baking sheet with the seam side down. 9. Brush the outside of each hidden burger with egg wash and sprinkle generously with sesame seeds. 10. Bake at 350°F for about 25 minutes, or until the bread is puffed and golden brown and the beef is fully cooked through. 11. Let cool slightly before slicing open, then serve and enjoy this completely contained, cheese-filled hidden burger! 🍔
