First, make a batter for potato pancakes. Peel the potatoes and shred them finely. Squeeze out excess water. Put the potato shreds in a large bowl and pour the hot milk over them. Add peeled and pressed garlic, eggs, salt, dried marjoram, ground pepper, and flour. Stir until combined and a semi-fluid batter forms.
In a non-stick frying pan about 10 inches (25 cm) in diameter, heat a tablespoon of lard or fat over medium-high heat. Scoop the potato dough with a ladle, pour it into the pan, and spread it in a thin layer. Fry each side until golden brown; it takes about two minutes to fry each side of the pancake. Transfer the fried potato pancakes to a plate lined with paper towels to drain the excess fat. Keep the pancakes warm.
Heat the slices of smoked meat. Heat half a tablespoon of lard or fat in a frying pan over medium-high heat, and fry the meat briefly on both sides. Reduce the heat to one-third, add four tablespoons of water, and let the meat heat through for another five minutes. Halfway through, flip the meat. Put the meat aside and keep it warm, like potato pancakes. Do not pour off any liquid left in the pan after heating the meat!
Drain the sauerkraut and, if necessary, cut it into shorter strips. Put it in the same pan in which you previously heated the meat. Heat the sauerkraut over medium-high heat for three to five minutes. Stir occasionally. Season sauerkraut to taste. If it is too sour, add a teaspoon of sugar.
Time to put together the final dish! Place a potato pancake on the plate. Put the warmed, smoked meat on the right half and top with sauerkraut. Finally, fold the potato pancake, so the meat and sauerkraut peek out a little.
