The recipe

Ingredients

Contains: milk, wheat, tree nuts, fish, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)

Directions

Prepare the base

  1. Brown the sliced onions in flour and butter until dark and crisp, but not burnt.

  2. Place the browned onions in a fish kettle and lay the fish on its belly.

  3. Cover the fish with lard or butter to prevent the skin from breaking.

Cook

  1. Pour 4 cups of water over the fish, steeped with thyme and sweet marjoram.

  2. Cover and cook slowly for 2 hours.

Finish and serve

  1. Just before serving, add the picked crabs (or oysters) and the walnut and mushroom catsup.

  2. Stir in the port wine and serve.

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

What each ingredient does

Onions
Browning them in flour and butter builds a dark, crisp, savoury base that flavours the stew.
Butter
Browns the onions and adds richness and fat to the finished dish.
Lard
Forms a protective layer over the fish skin, helping it hold together during slow cooking.
Crabs
Provide the main shellfish flavour and tender meat added at the end.
Port wine
Adds sweetness, depth and aroma to the finished stew.

The step that matters

Browning the onions. Onions must reach dark and crisp without burning. Burnt flour and butter turn bitter and spoil the whole stew, while pale onions add little colour or flavour.

Fit is the average pairing score against onion, flour, butter, fish, thyme, marjoram, crab. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
