(Recipe #3, page 28)
Highly recommended. Serve 1/2 pint [one cup] soup per person. One cup of water is used to cook one serving. Pour three quarts plus one pint water into a tin pot, and boil. Place one pound of good, boneless beef in the pot. Carefully skim the foam. Then add a whole chopped onion, one-fourth of a large celery root (alternately one-half of a celery root), and 4 heaping TBS of fine pearl barley. Cover tightly. When adding salt later, let soup cook 2-1/2 hours without removing lid. Do not boil too rapidly or too slowly.
To serve: Add flavorful egg yolk, nutmeg (if desired), and a level teaspoon beef extract to a [soup] tureen. Slowly add the soup to the tureen, stirring constantly, so the egg will not curdle.
