Remove meat from the pan and keep warm. Steam apple slices in hot frying fat for about 4 minutes. Steam spring onions and rosemary for about 2 minutes.
Deglaze everything with Aceto balsamico and about 100 ml water, bring to the boil and simmer briefly. Season sauce with salt, pepper and 1 pinch of sugar. Add the meat again and let it simmer for a short time. Serve with the potatoes.
