Heat the milk (not too hot) and dissolve the sugar and yeast cubes in it. Using a dough hook or by hand, mix the liquid with the flour, salt and egg in a large bowl. Knead the bread cubes into the dough. Knead into a ball with your hands.

Cover and leave to rest in a warm place for approx. 1 hour. Knead again with your hands and leave to rest for a further 30 minutes.

Form 3 long dumplings and steam for approx. 30 minutes. Traditionally, a kitchen towel was sometimes stretched over a pot of water and the dumplings steamed on it. However, it is easier with a steamer, a steamer insert or a sieve placed over the pot.

To cut the Bohemian dumplings, you can use a twine instead of a knife, which makes for a nicer cut.
