Why it works: Pepper and potato are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Prepare
Break the cold fish into flakes and moisten with cream. Season with pepper and salt.
Prepare mashed potatoes and hard-boiled eggs.
Assemble and steam
In a well-buttered mold, layer mashed potatoes, flaked fish, and thick slices of hard-boiled egg alternately.
Steam for 20 to 30 minutes, depending on the size of the mold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold fish
- Forms the flaked main body of the dish, providing its substance and flavor.
- Cream
- Moistens the flaked fish, keeping it tender and moist during steaming.
- Mashed potatoes
- Forms the layers that hold the mold together and add soft, starchy body.
- Hard-boiled eggs
- Adds firm slices and richness between the fish and potato layers.
The step that matters
Steam for the right time. Steaming for too long dries out the fish and can make the potato layers dense, while too little time leaves the center cold and loosely set. Matching the time to the mold size lets the custard-like binding of egg and cream set evenly throughout.
Swap the potato
How well each one fits the dish's main ingredients (fish, cream, pepper, egg):

Fit is the average pairing score against fish, cream, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
