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 ↓
Smoked Salmon Chartreuse
Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Soak the salmon to remove excessive salt.
Boil the rice as usual and stir in the curry powder mixed with 2 tablespoons of butter.
Make the filling
In a saucepan, make a thick sauce with the remaining butter, flour, and milk.
Add the flaked salmon, lemon juice, pepper, and onion juice to the sauce.
Assemble and bake
Line a well-buttered bread tin with the rice.
Pack the fish mixture into the tin, then add a layer of rice on top.
Steam or bake in a pan of water in the oven at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Forms the starchy base and top layer that holds the casserole together when set.
- Butter
- Enriches the sauce and rice with fat, adding richness and a smooth mouthfeel.
- Flour
- Thickens the milk into a stable white sauce that binds the salmon mixture.
- Milk
- Forms the liquid base of the sauce, adding moisture and a creamy texture.
- Smoked salmon
- Provides the main flavour and savoury protein that sets gently with the sauce.
The step that matters
Make the thick sauce before adding the salmon. Flour must be cooked into the butter and milk until thickened so the sauce binds the fish. A thin sauce will leave the casserole loose and watery once baked.
