Here I am sharing my favorite German potato dumpling recipe made from cooked jacket potatoes. If you like to peel your potatoes before cooking, that's ok!
Drain the potatoes and let the steam evaporate completely.
Take a large bowl and mash the potatoes with a potato ricer.
Take a large pot (or the pressure cooker you used) and bring at least 3-4 liters of salty water to a boil.
Add potato starch, salt, nutmeg, butter and egg yolks.
Knead all well together with your hand.
Form dumplings with your hands, tennis ball size. Repeat until you run out of batter.
Simmer the dumplings on very low heat (I am using 2 out of 10) for 20-25 minutes in a pot without a lid! The potato dumplings are done when they swim on the surface of the water.
