Mix the milk, flour and eggs well. If you like, you can also season with salt, pepper and nutmeg. Mix the whole thing with the hack. Fill the pig`s stomach with the mixture 3/4 full. Either sew up the opening of the pig`s stomach or simply tie it with a thicker ribbon (sausage ribbon). So that the pig`s stomach does not get stuck in the pot, simply put in a plate or a hanging sieve and place the stomach on it. Fill the pot with salted water and cook slowly for about 3 hours.
