Step 1
Preheat the oven to 250 degrees F.
Step 2
Grease an earthenware dish and set aside.

Fill a large pot with salted water - make sure there is enough water to cover the kohlrabi completely. Bring the water to a boil.
Step 4
Remove top leaves from the kohlrabi and peel. Boil the bulbs until tender, about 15 minutes, then drain (save the liquid) and cool.
Step 5
Stir in the egg yolk and sour cream. Season with salt and pepper.
Step 6
Alternate layers of kohlrabi, radish, and apple into the greased baking dish. Cover with the sauce, bake for 7 minutes, then place under the broiler until golden brown.
Step 7
Serve warm.
