Mock Turtle Soup

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

In a pot, combine minced meat, onion, carrots, celery, and water.
Add bay leaf, salt, and pepper.
Bring to a boil, then reduce heat and simmer for 1 hour.
Remove bay leaf and stir in lemon juice before serving.
