Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Forms the main body of the dish and provides its savory, flaky texture.
- Mashed potatoes
- Add body and softness, helping bind the fish into a cohesive mixture.
- Butter
- Adds richness and fat, giving a smoother mouthfeel and flavor.
- Milk
- Adds moisture so the mixture stays soft rather than dry.
The step that matters
Stir the mixture until very hot. Keeping the mixture in a hot water bath and stirring it evenly warms it through without scorching the bottom. Heat that is uneven or too low leaves cool pockets, while direct high heat can dry or scorch the proteins and starches.
Swap the potato
How well each one fits the dish's main ingredients (butter, milk, pepper):
- Potatothe original
- Capsicumfits about as well
- Tomatofits less well
- Asparagusfits less well
Fit is the average pairing score against butter, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
