Peel your potatoes and boil them in salted water till they’re tender, about 20 minutes. Drain and let cool.
Mash the potatoes smooth in a big bowl. Add flour, egg, and sea salt. Mix well.
Sauté chopped onions and mushrooms until soft, about 5 to 7 minutes. Add ground meat, flour, paprika, herbs, salt, and pepper. Cook till meat is browned, about 10 minutes. Let cool.
Scoop and flatten mashed potato mix. Spoon filling in the center, fold, and shape into patties.
Fry patties in heated oil in a skillet for 4 to 5 minutes on each side, until golden brown.
Notes
Serve them hot for the best texture and flavor contrast.
