Ingredients

Directions

The book says “a warm oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. Place the chopped onions in a strong earthen dish and add the white wine.

  3. Season the whiting with pepper and salt, then place it in the dish.

  4. Sprinkle the chopped parsley and mushrooms over the fish.

Bake and serve

  1. Pour the anchovy sauce over the top and sprinkle with brown bread crumbs.

  2. Bake in the oven for 30 minutes until nicely browned.

  3. Serve in the dish it was cooked in.

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

What each ingredient does

Whiting
Forms the main body of the gratin, cooking through to a tender, flaky texture.
Anchovy sauce
Adds savoury depth and moisture that keeps the fish from drying out in the oven.
Brown bread crumbs
Form a crisp topping that browns in the oven, adding texture over the fish.
White wine
Adds acidity and moisture, helping to steam the fish in the dish.
Mushrooms
Release moisture and savoury flavour into the dish as they cook.

The step that matters

Bake until nicely browned. Baking long enough lets the fish cook through and the crumb topping brown. Too little time leaves the fish underdone, while overbaking can dry the fish and toughen the crumbs.

Swap the onion
