Ingredients

Directions

Poach the fish

  1. Bring the water to a boil in a pan with vinegar, bay leaves, and salt.

  2. Add the halibut and simmer over low heat until the fish is cooked through and just beginning to come off the bones.

Make the soup

  1. Strain most of the stock into a clean pan, add prunes, and bring to a boil, leaving about half a cup in the pan with the fish and keep warm.

  2. Beat the softened butter into the flour, then whisk into the soup to thicken it.

  3. Simmer for 5 to 8 minutes.

  4. Add lemon juice and sugar, and season to taste.

Serve

  1. Serve the fish on a separate plate with the soup.

  2. Serve hot in small bowls to four diners with the rest of the meal.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Halibut steaks
Firm white flesh that holds its shape while poaching and flakes when fully cooked.
Prunes
Add sweetness, body and a soft texture to the soup as they simmer.
Butter
Adds richness and, with the flour, forms a roux that thickens the soup.
Flour
Thickens the soup when blended with butter and whisked into the stock.
Lemon juice
Adds acidity that brightens the sweetness of the prunes and sugar.
Sugar
Balances the acidity of the lemon and the tartness of the prunes.

The step that matters

Whisking the butter and flour into the soup. Flour clumps if added raw to hot liquid. Beating it smoothly into the softened butter first, then whisking it in, lets starch granules disperse evenly so the soup thickens without lumps.
