Apache Corn Soup

Peel the acorns and grind them. The outer part of the acorn is not used.

1 (2 1/2-pound) beef roast
2 quarts water
1 teaspoon salt
1 teaspoon pepper
1 cup ground acorn meal

Cover beef with water and bring to boil in a heavy pot. Simmer several hours until beef is very tender, adding salt and pepper. Remove the beef, while letting the pot continue to boil. Shred the beef, then mix it with the acorn meal. Add this mixture to the broth and simmer together until the broth bubbles creamy-white with yellow flecks.
