Planked Fish

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the plank

  1. Preheat the oven to 400°F (200°C) and warm the plank for 5 minutes.

  2. Butter the plank well and place the fish on it, skin side down.

Season and broil

  1. Brush the fish with melted butter and lemon juice.

  2. Broil the fish for about 15 minutes.

  3. Remove the plank for a minute to decorate the fish with tomato slices, green peppers, pimientos, and onions.

  4. Create a border of mashed potatoes around the fish using a pastry tube.

  5. If using, place oysters or clams around the fish and top each with buttered bread crumbs.

  6. Return the plank to the broiler and cook slowly for another 5 minutes until vegetables are done.

  7. If using potatoes, brush them lightly with egg yolk to brown quickly.

Serve

  1. Serve the fish on the plank on a large platter, garnished with lemon slices and parsley.

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

What each ingredient does

Fish
Forms the main body of the dish and cooks through under the broiler.
Melted butter
Adds richness and moisture, helping the fish stay tender and brown lightly.
Ripe tomatoes
Contribute juice and acidity that moisten the fish and balance the richness of the butter.
Mashed potatoes
Form a starchy border that holds its shape and browns under the broiler.
Egg yolk
Promotes quick browning of the potato border when brushed on.

The step that matters

Return the plank to the broiler and cook slowly. Fish is delicate and dries out quickly under strong heat, so a brief, gentle finish keeps it moist while the vegetables soften and the potatoes brown.
