Why it works: Butter and shrimp are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 2,931 recipes. Both carry 2,6-nonadienal, which smells cucumber, green. The science ↓
Fish Toasts
Ingredients
Directions
Prepare the fish
Remove oil, skin, and bones from the fish.
Chop the fish on a plate and knead it with a little fresh butter.
Make the fish topping
Mix a small quantity of white sauce with the minced fish and add the egg yolk.
Heat the mixture until thick enough to spread on hot fried toast.
Make the shrimp topping
For shrimps or prawns, melt butter in a small saucepan over low heat.
Add the shrimps and stir for a few minutes to absorb the butter.
Assemble and serve
Spread pounded shell extract on hot fried toasts and top with shrimps.
Dust with Nepal pepper and a little mace, then serve quickly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main savoury filling that is spread over the toast.
- White sauce
- Binds the minced fish into a spreadable, creamy mixture.
- Egg yolk
- Enriches the mixture and helps it set thick when heated.
- Fresh butter
- Adds richness and moisture to the minced fish.
- Shrimps or prawns
- Adds a sweet, delicate seafood topping to the toast.
The step that matters
Heat the mixture until thick enough to spread. Heating the white sauce and egg yolk mixture thickens it as the egg proteins set. If it is under-heated it stays runny and soaks into the toast; if overheated the egg can curdle and turn grainy.
Swap the mace
How well each one fits the dish's main ingredients (fish, butter, sauce, egg, shrimp, pepper):
- Capersfits better
- Parsleyfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against fish, butter, sauce, egg, shrimp, pepper. Candidates are from the same food group and used in at least 100 recipes.
