Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Bakes Fish
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Fillet the fish and dust thoroughly with flour, salt, and pepper.
Roll the pieces and place them in a flat dish.
Bake
Beat the egg and milk together, then pour over the fish.
Cut the butter and lemon into small pieces and place on top.
Cook in a slow oven at 300°F (150°C) for about 40 minutes.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Forms the main body of the dish, cooking to a flaky texture in the oven.
- Egg
- Binds with the milk to form a custard-like coating that sets around the fish.
- Milk
- Adds moisture and softness to the egg mixture, helping it set gently around the fish.
- Flour
- Dusts the fish so the coating helps the surface hold and brown slightly.
- Butter
- Adds fat and richness as it melts over the fish during baking.
- Lemon
- Adds acidity and aroma that brightens the rich milk and butter.
The step that matters
Dust the fish thoroughly with flour, salt, and pepper. An even coating of flour helps the egg and milk mixture cling to the fish and set into a cohesive layer instead of sliding off or pooling in the dish.
