L. S. Ayres & Company was an Indianapolis, Indiana, department store founded in 1872 by Lyman S. Ayres and taken over by his son Frederic in 1896. Its Tea Room opened in 1929 and became known for its Chicken Velvet Soup — a cream soup with no vegetables visible and chopped whitemeat chicken. Surprisingly, it's not as heavy as you might imagine. The Tea Room was closed in 1991 and the original downtown Ayres' store was closed in January 1992.

3/4 cup butter (1 1/2 sticks)
3/4 cup flour
1 cup warm milk

1 cup warm cream
1 quart chicken stock
1 1/2 cups chopped, cooked chicken
1/4 tablespoon salt
Dash pepper

Combine butter and flour, blending well. Add warm milk, pint of hot chicken stock and warm cream. After cooking well, add remaining ingredients.
