Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Fish Warmed with Gravy
Ingredients
Directions
Prepare
Cut the fish into moderately-sized pieces, removing skin and bones.
Mash the potatoes with the butter and milk until smooth.
Make the gravy
Place the fish in a stew pan with the brown sauce and heat gently by the fire.
Serve
Form a firm wall of mashed potatoes around the edge of a serving dish.
Once the fish is heated, place it and the gravy in the center of the potato wall.
Serve hot, ensuring the potato wall is neat for presentation.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Forms the main body of the dish, flaking into tender pieces when gently heated.
- Brown sauce
- Provides the savory gravy that moistens the fish and carries its flavor.
- Potatoes
- Mashed to form a firm, smooth wall that holds the fish and gravy in place.
- Butter
- Adds richness and fat to the mashed potatoes, improving flavor and smoothness.
- Milk
- Loosens the mashed potatoes, helping them become smooth and easy to shape.
The step that matters
Form a firm wall of mashed potatoes. Potatoes must be mashed smooth and stiff enough to hold their shape; if they are too loose, the wall slumps and the gravy spreads across the plate.
Swap the potato
How well each one fits the dish's main ingredients (fish, sauce, pepper, butter, milk):

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