Harengs Frais a LA Sauce Blanche

Ingredients

Directions

Prepare

  1. Scrape and clean the herring, then sprinkle with coarse sea salt.

  2. Preheat a gridiron and place the herring on it, ensuring the gridiron is warm to prevent sticking.

Cook and serve

  1. Melt butter in a saucepan until it is fully liquid.

  2. Pour the melted butter over the hot herring.

  3. If desired, add chopped capers or mix in 1 teaspoon of French mustard for a variation.

  4. Alternatively, serve the herring over tomato sauce.

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

What each ingredient does

Fresh herring
Forms the main body of the dish, cooking to a moist, flaky texture.
Butter
Melted over the hot fish to add richness and a smooth, fatty finish.
Coarse sea salt
Seasons the fish and draws out surface moisture before cooking.

The step that matters

Preheat and warm the gridiron. A properly warm gridiron sears the herring's surface so it releases cleanly. Placing fish on a cold grid lets it stick and tear, and the skin can break apart.

Swap the mustard

The recipe marks mustard as optional. How well each one fits the dish's main ingredients (butter, capers, tomato, sauce):

  1. Shallotfits better
  2. Mustardthe original
  3. Chivefits about as well
  4. Welsh onionfits less well

Fit is the average pairing score against butter, capers, tomato, sauce. Candidates are from the same food group and used in at least 100 recipes.
