How to make
Cut the potatoes into round slices. Season the ribs with soy sauce, savory, paprika and black pepper. Rub them well, as well as the potatoes, with the sauce and a little pepper.
Cut the leeks into round slices. Arrange some potatoes, a rib and leek slices on a sheet of foil. If needed, sprinkle on additional spices.
Sprinkle with a little olive oil and wrap well with the foil. Put the foil packets in the oven for about 50 min. If you'd like them to have a crust, open the foil toward the end and let them crisp.
