Why it works: Lettuce and cucumber match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 1,409 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
Ingredients
Contains: egg, milk, tree nuts, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
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 and bake
Wash and dry the fish.
Place it on a buttered baking tray and sprinkle with lemon juice, salt, and pepper.
Cover with greased paper and bake at 350°F (175°C) for 20 to 30 minutes.
Cool and decorate
Remove the skin carefully without breaking the fish and let it cool completely.
Spread mayonnaise sauce all over the fish.
Decorate with rings of hard boiled egg, capers, and pickled walnut cut into fancy shapes.
Serve
Lift the fish onto a bed of shredded lettuce and sliced cucumber or any seasonal salad.
Garnish with egg yolks passed through a sieve or thin slices of tomato and chopped aspic jelly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the flaky main body of the dish, which is cooked gently and served whole.
- Butter
- Greases the tray so the fish does not stick and adds richness to the surface.
- Eggs
- Hard boiled eggs add firm, pale garnish and rich flavour to the decoration.
- Mayonnaise sauce
- Coats the cooled fish with a rich, creamy layer that adds moisture and fat.
- Lemon
- Its juice adds acidity that brightens the mild flavour of the fish.
- Pickled walnut
- Adds a sharp, tangy note that contrasts with the rich mayonnaise.
The step that matters
Remove the skin carefully without breaking the fish and let it cool completely.. Cod is delicate and flakes easily when hot, so tearing it while skinning ruins the presentation. Letting it cool fully firms the flesh so it holds its shape when lifted and coated with mayonnaise.
Flavor stand-ins for the cucumber
How well each one fits the dish's main ingredients (butter, lemon, pepper, egg, lettuce, capers, sauce):

- Cucumberthe original
Fit is the average pairing score against butter, lemon, pepper, egg, lettuce, capers, sauce. 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).
