Drain shrimps on a sieve. Wash the cucumber, cut into thin slices and quarter them. Mix shrimps, cucumber slices and peppercorns. Mix mayonnaise, milk, lemon juice and curry and season with sugar, salt and pepper.
Add to the shrimp and cucumber salad and fold in. Fill into glasses and serve garnished with ice crevices, chives, dill and prawns as desired. For the shrimp-cucumber salad variation, fill into glasses and garnish with lamb's lettuce and prawns to taste.
Spread a little curry sauce on top and serve. Add the rest of the sauce.
