Process the cucumber, yoghurt, mineral water, wasabi and the lemon juice in a blender to make liquid. Season to taste with cayenne pepper, salt and black pepper and strain through a fine sieve, set aside.
Remove the intestines from the shrimp and fry them briefly on both sides with the ginger and garlic at a slightly higher temperature, depending on the thickness of the shrimp, season with salt and pepper. Now cover evenly with the wine and let it boil down briefly on a low heat. Meanwhile, turn the prawns once.
Mix the cucumber wasabi shooter once until foamy and divide into smaller glasses. Serve with 2 prawns, either warm or cold, as an amuse or a small starter. Leave the ginger and garlic in the pan.
