Simple British Beef Burgers Fire up the barbecue with these simple British beef burgers that focus on quality meat. Combine 500g of premium British beef mince with a finely diced small onion, one egg yolk, and a splash of Worcestershire sauce in a large mixing bowl. Shape the mixture into four thick patties and press a small indentation in the centre of each to ensure even cooking. Chill the patties for twenty minutes to help them hold their shape on the grill. Fry or grill for five minutes on each side, then serve inside toasted brioche buns. find the precise measurements and tips at Mary Berry Recipe
