Instructions

1. 1
   Beat the egg. Mix and knead in flour until you have a very stiff dough.
2. 2
   Roll the dough out into a thin sheet.
3. 3
   Sprinkle the dough with a good amount of flour to prevent it from sticking to itself. Tightly roll up the dough to make a log.
4. 4
   Use a sharp knife to cut the log cross-wise into thin slices, similar to how you would slice cabbage for slaw. Unroll the noodles and toss with flour.
5. 5
   Add the noodles to boiling soup. Simmer for 10 minutes.
