Peel and finely chop the onion. Clean and wash the radicchio, drain well and cut into wide strips. Cook the pasta in approx. 2 l boiling salted water (1 teaspoon salt per litre) according to package instructions until firm to the bite.
Roast pine nuts in a pan without fat until golden brown. Remove. Heat the oil in the pan. Brown the onion and diced ham. Add the radicchio and fry over medium heat for 3-4 minutes.
Take off about 50 ml of pasta water with a ladle. Add it to the radicchio with white wine, olives and pine nuts and boil down a little.
Meanwhile, wash the orange hot, dry it and rub half of the peel off. Grate cheese roughly. Wash basil, shake dry and pluck the leaves. Stir the cream into the radicchiomix.
Drain the pasta and put it back into the pot. Mix the radicchiomix, cheese and basil well into the pasta. Season to taste with salt and pepper. Serve and sprinkle with orange peel.
