1Sift flour with salt, and if you like, spices. Mix egg and water and add slowly to dry mixture. Beat hard until smooth (batter will be quite thick). Bring about 2 quarts of well-salted water (or chicken or beef broth) to a slow boil in a large, heavy saucepan. Balance a colander on the rim of a saucepan so that it is well above the water. Spoon about 1/3 of batter into colander, then carefully press through holes, letting spatzle fall into water. Cook for 3-4 minutes, lift out with a slotted spoon, and keep warm while cooking remaining spatzle. Toss spatzle with melted butter and serve hot.
