Method

Heat a glug of oil in a large frying pan and add the onion. Fry for 5 minutes until starting to soften, then add the garlic. Fry for a further 2-3 minutes, then remove from the frying pan to a plate and leave to cool completely.
In a large mixing bowl, mix the beef, cooled onion and garlic, egg, mustard, cayenne and breadcrumbs. Season with salt and pepper, then divide the mixture into 4.
Shape each portion into a large patty, place a quarter piece of mozzarella in the centre of each, then form the mix carefully around the mozzarella to encase it fully in a burger shape. Put the burgers on a plate, cover with cling film and chill for 30 minutes. Heat the oven to 200°C/180°C fan/gas 6.

Heat a large frying pan with a little oil. When the oil is almost smoking, add the burgers. Fry for 4-5 minutes on each side until the burgers are coloured, then put them in a baking tray. Transfer to the oven and cook for 10 minutes until the beef has cooked through and the mozzarella has melted (test by piercing one carefully with a sharp knife). Leave to rest for 5 minutes, then serve in buns with your choice of toppings and sides.
