1. 1
   Mix all the ingredients for the mayonnaise, except the lemon juice, together in a bowl. Season to taste with the lemon juice, salt, and pepper.
2. 2
   Heat the grill to high. Line a baking tray with baking parchment and arrange the corned beef into four piles on it, then top with the cheese and grill until melted and bubbling.
3. 3
   Butter both sides of all the bread slices. Heat a frying pan over a medium heat and toast the bread slices on both sides until golden. Generously spread the mayonnaise over one side of each bread slice. Top four of the slices, mayonnaise-side up, with the cheese-topped corned beef and the sauerkraut, then sandwich with the remaining bread slices, mayonnaise-side down. Secure with cocktail sticks, then slice in half to serve.
