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 stew as tender flakes of protein.
- Milk
- Provides the liquid base and creamy texture of the stew.
- Flour
- Thickens the milk into a smooth, body-giving sauce when heated.
- Egg
- Stirred in at the end, it adds richness and slight thickening to the stew.
- Butter
- Adds fat, richness and a rounded flavour to the finished stew.
The step that matters
Add the flour paste to the hot stew. Flour must be mixed smooth in cold liquid first, then added to hot liquid and stirred, or it clumps. Starch swells and thickens only when heated, so the stew should be kept hot while it thickens.
Swap the potato
How well each one fits the dish's main ingredients (milk, flour, egg, butter):
- Chivefits about as well
- Potatothe original
- Leekfits about as well
- Asparagusfits about as well
Fit is the average pairing score against milk, flour, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
