Preheat the oven to 190Β°C. Wash potatoes, dry them and roast with skin on for approximately 35min, check with fork if tender inside, before taking them out. Cut the baked potatoes in half and allow to cool.

Scoop out the potato from the skins, you should have around 400g.
3)
Combine potatoes, milk and half of the sour cream with the eggs. Blend for few seconds, being careful not to overwork mixture and make it runny. Add the flour and baking soda, salt and pepper to taste, then gently fold in with a spatula.
