Grate the cabbage, salt it, and leave to stand for 20-25 minutes to release its liquid.
Squeeze out the excess liquid thoroughly by hand.
Heat the lard, add the finely chopped onion, and sauté until translucent and golden.
Add the squeezed cabbage, white pepper and sugar, and cook covered, stirring often, for about 20-25 minutes, until nicely golden, taking care it doesn't burn.
Meanwhile, knead the flour, eggs, a pinch of salt and a little water into a firm dough, roll out thinly, and cut into squares.
Cook the pasta squares in boiling salted water for 3-4 minutes, until they rise to the surface, then drain.
Toss the cooked squares with the braised cabbage, and heat through together.
Serve hot.
