Rinse the buckwheat, simmer it covered in 300 ml of water with a pinch of the salt for 15 minutes until all the water is absorbed, then let it cool.
Mix the cooled buckwheat with the pork, onion, garlic, egg, 9 g of salt and the pepper, and knead until the mixture holds together.
With wet hands shape 12 oval patties about 2 cm thick and roll them in the flour.
Heat the oil in a frying pan over medium heat and brown the patties for 2-3 minutes per side, then move them to a baking dish in one layer.
Whisk the tomato paste, sour cream, 250 ml of water and the remaining salt into a smooth sauce and pour it over the patties.
Cover with a lid or foil and bake at 180C for 30 minutes, then uncover and bake 5-10 minutes more.
Serve 2 patties per person with the sauce, with a cucumber and tomato salad or pickles.
