Defrost the prawns if necessary. For the devil's marinade, mix Tabasco, 1 tablespoon paprika and 3-4 tablespoons of oil. Rinse shrimps, dab dry and marinate in the marinade for at least 30 minutes.
Meanwhile clean the kohlrabi and put the tender inner leaves aside for garnishing. Peel, wash and chop the kohlrabi and potatoes. Peel and chop the onion. Heat butter in a large pot.
Sauté the kohlrabi, potato and onion. Deglaze with wine and 400 ml water. Bring to the boil, stir in broth and simmer covered for about 15 minutes.
Add cream and puree the soup with a hand blender. Season to taste with salt and pepper.
Heat a pan without fat. Fry the prawns in it over medium heat while turning for 2-3 minutes. Season with salt. Serve the soup, add the prawns and small plucked kohlrabi leaves.
