Beat egg slightly with salt, add enough flour to make a stiff dough; work it well for fifteen or twenty minutes, adding flour when necessary. When the dough is smooth place on slightly floured board and roll out very thin and set aside on a clean towel for an hour or more to dry. Fold in a tight roll and cut crosswise in fine threads. Toss them up lightly with fingers to separate well, and spread them on the board to dry. When thoroughly dry, put in a jar covered with cheese cloth for future use. Drop by handfuls in boiling soup, ten minutes before serving.
Noodles for vegetables or for puddings are made in the same way, but to each egg, one-half egg-shell full of cold water may be added. The strips are cut one-half inch wide.
