Decided to make burgers last weekend just before I start my night shifts. Sudden craving for good burger patties so decided to try a recipe by marcus wareing on http://www.greatbritishchefs.com/recipes/cheeseburger-recipe-caramelised-onions. I adapted a tiny part of the recipe and I have to say it is one of the most yummiest burger patty I have eaten so far.
1. For the burger patties: Mix together the burger ingredients. Fry a little of the mixture to check the seasoning and adjust as necessary. Shape into 4 patties and refrigerate.
2. For the caramelised onions, melt the butter in a medium-sized frying pan. Add in sliced onions, thyme and salt. Cook for approximately 20-25 minutes until golden and sticky.
3. Heat 1 tablespoon of oil in a large frying pan and brown the burgers until cooked through, about 6-7 minutes each side. Remove them from the heat and place a slice of cheese on top of each one to melt gently.
4. Brush some butter on the burger buns and toast lightly on a frying pan. Add caramelised onions (tomatoes, mushrooms etc as you like) and sandwich together.
