Onions peel and roughly chop. Wash the meat, dab dry and cut into approx. 2 cm cubes. Steam onions in hot lard until golden brown. Dust with paprika. Deglaze with 1/2 cup of water (paprika becomes bitter if fried too strongly).
Salt the meat cubes and add tomato paste. Add it to the onion mixture and let it draw juice in a closed pot at low heat. Then remove the lid. Loosen the roast with a spatula, let the roast liquid boil down.
Deglaze the meat with approx. 3/4 litres of water (it should be just covered with liquid). Cook at low heat for about 1 hour. In the meantime, peel, wash and dice the potatoes.
Add to goulash and cook for another 20 minutes. Season again with salt and paprika.
