1902 - With a Saucepan Over the Sea

Scotland - Cocka Leekie

DDV CULINARY

This is the oldest recipe for soup known, as it dates back to the fourteenth century.
Wash and trim 1 dozen leeks, cut them in pieces half an inch long,
discarding roots and tops, then fry them in 1 ounce of butter,
with 2 stalks of celery and 1 carrot, cut fine.
When brown but not burnt, add 1 1/2 quarts of chicken broth
and 1 cup of cooked chicken, cut into dice.
Simmer, covered, 2 hours, then add salt, pepper, and yolk of an egg,
blended with a little of the broth, first, before adding to the soup.
