Peel the kohlrabi, cut into thin slices and place in a saucepan. Fill up with the water and season with salt, 1 teaspoon nutmeg, curry and turmeric (the potato-yellow color should be retained). Cover the pot with the lid and bring the water to a boil. Cook the kohlrabi al dente, approx. 10 min.
Meanwhile, put the cream and crème fraîche in a bowl and mix or season with 1 teaspoon nutmeg, the thyme and pepper. Pour the cream evenly into a baking dish and spread the pre-cooked, drained kohlrabi slices over it. Finally, sprinkle the diced ham and the grated Gouda cheese on top. Cook for approx. 40 minutes.
Great homemade meatballs go well with this.
Tip: For the vegetarian version, simply leave out the ham cubes.
