1. Boiled Fish.

Ingredients

Directions

Prepare the fish

  1. Use thick pieces of large fish for boiling, or if small fish are used they may be boiled whole.

  2. Wrap the fish in cheesecloth to prevent breaking apart, and plunge into boiling water.

Poach

  1. Add salt and vinegar to water in proportion of 1 tablespoonful of salt and two of vinegar to three quarts of water. Use enough water to cover the fish.

  2. Do not let the water boil after fish is in.

  3. The fish is done when the flesh leaves the bone or when the flesh flakes apart easily.

  4. The usual time for a thick piece is 30-40 minutes.

Make the sauce and serve

  1. Make as for white sauce, adding the beaten eggs just before taking from fire and stirring until well thickened.

  2. Add lemon juice just before serving.

  3. The sauce is suitable for boiled fish and vegetables.

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

What each ingredient does

Eggs
Beaten into the white sauce, they thicken it as they set with gentle heat.
Flour
Forms the base of the white sauce, thickening it as it cooks.
Milk
Forms the liquid base of the white sauce, giving it a smooth, creamy body.
Lemon juice
Adds acidity that brightens the rich sauce.

The step that matters

Keep the water below a boil once the fish is in. Boiling water toughens and breaks up delicate fish flesh, so gentle simmering keeps the pieces intact and tender while they cook through.

Swap the lemon
