If we serve ribs with potatoes, then peel it, cut it into cubes. Lightly salt the potatoes, grease with vegetable oil, mix. Grease a saucepan or a frying pan with a thick bottom with vegetable oil. Put the ribs on the edges, put the potatoes in the center. Put in a preheated 220 deg oven. After 20 minutes, gently stir the potatoes. After another 20 minutes, if the potatoes are not ready, take out the ribs, cover with foil and remove to a warm place, mix the potatoes again and put them in the oven until ready.
