Wash the potatoes thoroughly and prick several times with a fork all around. Place the potatoes on a baking tray lined with baking paper and bake in a preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see
manufacturer) bake for about 1 hour.
In the meantime 1⁄2 l water with broth boil up. Wash the turkey breast and cook covered in it for about 20 minutes at low heat. Lift the turkey breast out of the broth and pluck into pieces. Clean and wash spring onions and cut into fine rings.
Let the potatoes cool down a little and cut them in half lengthwise. Using a spoon, remove some of the inside of the potatoes and mix with 4 tablespoons of sour cream. Sprinkle potato halves with spring onions, except for 1 tablespoon, and sprinkle with Worcester sauce.
Spread the potato sour cream mixture into the potato halves. First sprinkle turkey and then cheese over it.
Bake the potatoes in a preheated oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer) for approx. 20 minutes. Sprinkle with rest of spring onion rings. Add the rest of the sour cream.
