Add the soaked codfish pieces.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main flavour and protein, flaking into the liquid as it cooks.
- Eggs
- Set when heated, adding body and richness to the stew.
- Flour
- Starch that thickens the liquid as it heats, giving the stew its body.
- Milk
- Adds creaminess and moisture, combining with flour to form the thickening.
- Butter
- Adds fat for richness and a smooth mouthfeel.
The step that matters
Stirring the flour and milk into the skillet. Flour thickens only when its starch is heated in liquid. Mix it smoothly into the hot mixture and keep stirring, or it may clump and the stew may stay thin or lumpy.
