Ruben Burger

Method

1. Prepare the beef patty: mix ground beef (at least 30% fat) with salt, pepper, and a pinch of spicy paprika. Form a patty of about 250 g, pressing out air.
2. Heat a grill or griddle with oil. Cook the patty on high heat, searing both sides. Cook to medium doneness, not rare.
3. Slice an onion. Use half to make the burger sauce: finely chop the onion and a pickle. Mix with ketchup, mayonnaise, and a splash of pickle juice. Season with pepper.
4. Fry the remaining onion slices on the grill until golden and soft.
5. Slice salami into thin strips and fry on the grill until crispy.
6. Fry an egg in a ring on the grill, seasoning with salt and pepper. Cook until the white is set and the yolk is runny.
7. Toast the burger bun on the grill until lightly charred.
8. Slice a firm tomato and season with salt and pepper.
9. Assemble the burger: spread burger sauce on the bottom bun. Place the patty, then crispy salami, fried onions, pickles, tomato slices, and the fried egg on top. Cover with the top bun.
10. Serve immediately.
