Wash and drain the scampi. Bring 1/2 litre water, lemon juice, some salt and caraway seeds to the boil. Add the scampi and let them simmer for about 5 minutes at low heat. Remove from the stock and drain.
Loosen the scampi (except for the tail) from the shell, cut them open and remove the intestines. Cut the baguette into pieces. Drain the mozzarelli on a sieve and arrange them on 8 wooden skewers alternating with baguette and scampi.
Peel the garlic and press it through a garlic press or chop it finely. Mix with fat and a pinch of salt. Heat the fat in a frying pan and fry the skewers while turning them until the baguette pieces are crisp.
Season with lemon pepper. Clean, wash and drain the watercress. Arrange skewers with watercress and lemon slices on plates. Garnish with nasturtium.
