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.

Prepare

  1. Place the leftover fish in a pot.

  2. Add enough water to cover the fish.

  3. Season with salt and pepper.

Simmer and serve

  1. Bring to a boil, then reduce heat and simmer for 20 minutes.

  3. Strain the soup and serve hot.

What each ingredient does

Leftover fish
Gives the soup its main flavor as it cooks and releases its taste into the water.
Water
Forms the broth and carries flavor from the fish throughout the soup.

The step that matters

Reduce to a gentle simmer after boiling. A hard, rolling boil breaks up the fish and clouds the broth, while a gentle simmer keeps the soup clearer and the fish tender.
