There isn't really a recipe since every time is a little different. I essentially take one egg per person (maybe less if not my family), add salt and pepper and a very little water. You beat this and then add enough flour to make a soft dough. There is debate over whether you add a smidge of baking powder (I do, my mom does not, my grandmother did, not sure about my dad). You drop this by small bits (about 1/2 teaspoon) into simmering stock. This is the time consuming part but the results are definitely worth it!!
It's a sure bet for a meal in any season but especially when it's cold outside.
