Bring the meat stock to a boil and cook the tortelloni in it, then drain.
Rub a saucepan with the clove of garlic. Mix the crème fraîche with the milk in the saucepan, bring to the boil and add the tortelloni. Season the sauce with salt, pepper, nutmeg and spices and let it simmer for a few minutes. Chop the ham and chives, add to the tortelloni and stir in.
Serve immediately and serve with toast or white bread.
