How To make Grandma Vanicek's Czechoslovakian Potato Dumplings

6 md Potatoes
1 Egg yolk
1 1/2 ts Salt
1/2 All-purpose flour
These are *not* fluffy dumplings as in chicken and dumplings. They are a "sturdy" potato dumpling served as a side dish to meat, and usually with a sweet sauerkraut/carraway/honey dish as the vegetable. * * * Boil peeled potatoes in small quantity of water. Drain potatoes thoroughly. Rice potatoes through hand held masher/ricer. Let potatoes cool. On floured board, gradually add flour working mixture into dough with hands. Shape potato mixture into a long roll and cut into 10 slices. Drop dumplings into boiling water and boil gently about 5 minutes. Drain dumplings on paper towel. The dumplings are fully cooked after the boiling process, but traditionally, Czechoslovakians then melt butter in a heavy frying pan, and fry the dumplings until they are lightly browned on all sides.
