Combine ingredients and work into a dough. Roll out with a rolling pin to desired thickness and cut into noodles. Or use a noodle cutting machine. Add flour generously. Spread out noodles on a clean dishtowel and let them dry at room temperature for 1 to 2 hours.
Roast:
7 lbs. beef roast (rump, arm or chuck)
1 package dry onion soup mix.
salt and pepper

Sprinkle soup mix, salt and pepper over roast. Add water to half-way up the roast. Cover with aluminum foil. Cook 6 hours at 250°F.
Remove meat from pan and set aside. Drain broth into a large pot. Skim off fat. Bring to a boil over medium heat and add the noodles. Add water as needed. Continue to cook over medium heat, stirring often, until noodles are done and broth has thickened.
