Bring 3/4 litres of water and a little salt to the boil in a saucepan. Clean, wash and cut the leek into rings. Put the leek into the boiling water and cook covered for about 8 minutes
In the meantime preheat the grill. Mix the potato pancake dough and egg. Dab the pork steaks dry and place them in an ovenproof dish. Spread 1 heaped tablespoon of potato pancake dough (approx. 60 g) on each pork steak. When the grill has reached its temperature, grill the steaks on the middle rack for 12-15 minutes
Pour the leek onto a sieve, collect the vegetable water. Measure out 1/2 litre of vegetable water. Melt the fat in the pot, sweat the flour in it. Pour in the vegetable water while stirring. Bring the sauce to the boil and simmer for about 5 minutes. Stir in between
Heat the oil in 2 large pans and bake about 12 small Rösti from the remaining potato pancake dough. Besides, stir brunch into the leek sauce, season with salt and pepper. Add leek to the sauce and heat up briefly. Arrange smoked pork loin with rösti crust, leek vegetables and rösti on plates. Sprinkle leek vegetables with nutmeg as desired
