Boil egg hard for 9 minutes. In the meantime, clean, wash and pat dry the fennel. Cut the fennel (preferably with a slicer) into wafer-thin slices. Heat 100 ml water in a wide pot.
Cook the fennel slices for about 5 minutes at low heat. Meanwhile peel the orange so that the white skin is completely removed. Cut 3/4 of the orange into slices. Squeeze the rest of the orange and collect the juice.
Roast the hazelnut leaves in a pan without fat until golden brown. Clean the rocket and basil, wash and shake dry. Pluck the basil leaves from the stalks. Remove the fennel from the stock and let it drain.
Mix 5 tablespoons fennel stock, orange juice, yoghurt and honey. Season with salt and pepper. Cut the egg into slices. Mix fennel, rocket, orange slices, ice cream slices and basil. Drizzle with yoghurt dressing.
Sprinkle with hazelnut leaves and pink berries. Serve with roasted wholemeal baguette (ask the baker for lactose-free variety).
