Ingredients

Directions

Prepare

  1. Weigh the fish and bind it in thin muslin or coarse cheesecloth.

  2. Fill a large kettle with water and add coarse sea salt to taste.

Cook

  1. Bring the water to a boil, then reduce heat slightly before adding the fish.

  2. Add vinegar to the water for a large fish.

  3. Keep the water boiling and cook for 6 minutes per pound, plus an additional 6 minutes for large fish.

  4. Avoid piercing the fish; ensure the water remains at a steady boil.

Serve

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

What each ingredient does

Fish
Is the main protein, cooked gently in simmering water until it turns firm and flaky.
Vinegar
Added to the cooking water, it helps keep the fish's flesh firm and intact while it cooks.
Butter
Served as drawn butter, it adds richness and moisture that complements the mild fish.
Hard-boiled eggs
Sliced over the fish, they add a soft, rich texture and mild, creamy flavor.

The step that matters

Keep the water at a steady boil without piercing the fish. Piercing the fish lets juices escape and dries the flesh, while letting the water drop below a steady boil slows cooking unevenly. Keeping the water steadily boiling and the fish intact helps it cook evenly and stay moist.

Swap the tomato

The recipe marks tomato as optional. How well each one fits the dish's main ingredients (fish, vinegar, butter, egg, parsley, lemon, ketchup):

  1. Shallotfits better
  2. Horseradishfits better
  3. Chivefits better
  4. Tomatothe original

Fit is the average pairing score against fish, vinegar, butter, egg, parsley, lemon, ketchup. Candidates are from the same food group and used in at least 100 recipes.
