Lobster burger with thermidor mayonnaise

Preparation method

1. For the cheese slice, melt the cheese and milk together in a saucepan over a low heat. Stir the mixture until smooth, then stir in the flour, breadcrumbs and mustard and cook for a few minutes. Stir in the Worcestershire sauce, salt and freshly ground black pepper and set aside to cool.

2. Blend the mixture in a food processor with the eggs and egg yolks to form a soft dough.

3. Roll the dough out on a lightly floured surface, transfer to a baking tray and leave to chill for four hours. Cut the cheese slice into four squares big enough to top the burgers.

4. For the lobster burger, mix the mackerel, lobster meat, parsley and garlic together in a bowl and season with salt and freshly ground black pepper. Shape the mixture into six burgers using your hands and set aside to rest for at least one hour.

5. Place the beef tomato slices onto a baking tray, drizzle with the vinegar, sprinkle with a pinch of sugar and the thyme leaves and leave to chill in the fridge for 2-3 hours.

6. For the mayonnaise, mix the smoked paprika, English mustard powder and vegetable oil together in a bowl.

7. Whisk the egg yolks, white wine vinegar and Dijon mustard together in a separate bowl, then slowly whisk in the vegetable oil mixture until all of the oil has been added and the mayonnaise has thickened. Stir in the lemon juice and salt.

8. For the kohlrabi, mix the kohlrabi, onion and salt together in a bowl and set aside for 30 minutes. Rinse the kohlrabi and onion and pat dry with kitchen paper.

9. Mix the rinsed kohlrabi and onion with the caraway seeds in a bowl. Season, to taste, with salt and freshly ground black pepper.

10. Blanch the lobster claws in boiling water for three minutes, then remove and place into iced water for 30 seconds to cool. Remove the meat from the claws.

11. Heat the pork fat in a saucepan, add the lobster claws and cook on a gentle heat for 5-6 minutes.

12. Preheat the grill to high.

13. Heat the olive oil in a frying pan and fry the burgers for 1-2 minutes on each side. Place the burgers onto a baking tray, top with the cheese slice and grill until the cheese is golden-brown.

14. To serve, spread each burger bun with the mayonnaise, top with some lettuce, tomato slices, a burger and a lobster claw.
