Meanwhile, peel the kohlrabi and cut into small pieces (approx. 1-2 cm).
Bring the vegetable stock with water and coconut milk to the boil and cook the kohlrabi in it for 15 minutes. Stir frequently so that the milk does not burn. Add the can of corn and season with chilli flakes, nutmeg and the finely chopped leaves of basil and lemon balm.
