Where can someone find a good recipe for celery soup?

Ingredients:

- 1 bunch of celery, chopped

- 2 cups of chicken broth

- 1 cup of milk

- 1/4 cup of all-purpose flour

- 1/4 cup of butter

- 1 teaspoon of salt

- 1/2 teaspoon of black pepper

Instructions:

1. In a large pot, bring the chicken broth to a boil.

2. Add the celery and cook until it is tender, about 10 minutes.

3. In a separate bowl, whisk together the milk, flour, salt, and pepper.

4. Slowly whisk the milk mixture into the pot with the celery and chicken broth.

5. Bring the soup to a simmer and cook until it is thickened, about 5 minutes.

6. Serve the soup immediately, garnished with additional celery leaves or croutons.

Tips:

- To make a vegan version of this soup, you can substitute vegetable broth for the chicken broth and use a plant-based milk, such as almond milk or oat milk.

- For a richer soup, you can add 1/2 cup of heavy cream to the soup just before serving.

- If you don't have all-purpose flour on hand, you can use cornstarch or arrowroot powder as a thickening agent.
