Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main body and flavour of the dish.
- Eggs
- Set during stewing to add richness and body to the liquid.
- Flour
- Thickens the liquid when mixed with milk and stirred in.
- Milk
- Combines with flour to form a smooth, thickening base that adds creaminess.
- Butter
- Adds fat, richness, and a smooth mouthfeel to the stew.
The step that matters
Adding the flour and milk thickening. Flour mixed into cold milk can clump, and it must be whisked smooth before going into the simmering liquid. Stirring as it goes in helps the starch disperse evenly and thicken without lumps.
