Lamb patty hamburger

Ingredients:

Cutlets:

• 450 g of ground beef
• 450 g of minced young lamb
• Salt and ground black pepper
• 1 tbsp. grape seed oil
• 4 slices feta cheese, 0.5 cm thick.
• 3 tbsp softened butter
• 4 brioche buns
• Lettuce and tomatoes for hamburgers

Sauce:

• 1/2 cup sour cream
• 1/4 cup peeled and finely diced cucumber
• 2 tbsp chopped red onion
• 2 tbsp diced tomato (skin removed)
• 1 teaspoon of salt
• 1 pinch of ground white pepper

Preparation:

1. For cutlets: In a bowl, combine the beef and lamb. Season with salt and pepper, then remove from the bowl and form into 4 patties, each weighing 225g.
   
   To cook the patties, heat the oil in a large skillet over high heat until it begins to smoke. Then reduce the heat to medium and add the patties.
   
   Fry for 5 minutes on one side, then flip and fry the other side. When frying the second side, sprinkle the patties with feta cheese.
2. For the sauce: While the cutlets are frying, combine the sour cream, cucumbers, onions, tomatoes, salt, and pepper in a bowl. Taste and season with additional spices, if desired.
   
   Heat a second skillet over medium heat. Butter the insides of the buns, then place them in the warm skillet and toast until crisp, 2-3 minutes.
   
   Once the buns are ready, assemble the burgers by placing lettuce, tomato, and patty on the buns, pour sauce on top, and enjoy.
