Ingredients

Directions

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

Prepare

Preheat the oven to 350°F (175°C).

Assemble and bake

In an earthen dish, layer the prawns or shrimp, bread crumbs, vinegar, tomato ketchup, and butter.
Season each layer with salt and pepper, making the top layer of crumbs.
Bake for 20 minutes.

Serve

Serve hot in the same dish.

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

What each ingredient does

Prawns or large shrimp: Provide the main protein, which firms and turns opaque when cooked.
Dried bread crumbs: Absorb the liquid and give the dish its soft, scalloped body.
Vinegar: Adds sharp acidity that brightens the rich, buttery layers.
Tomato ketchup: Adds sweetness and tomato flavour, with some moisture.
Butter: Adds fat for richness and helps the top crumbs brown in the oven.
