Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Canned salmon
- Provides the main protein and flavour, heated through before serving.
- Butter
- Adds richness and a rounded flavour, and forms the base of the sauce.
- All-purpose flour
- Thickens the sauce as its starch swells in the hot butter and liquid.
The step that matters
Slowly add the boiling water while stirring. Flour must be evenly dispersed in the melted butter before liquid is added, or lumps will form. Adding the water gradually and stirring constantly lets the starch hydrate smoothly, so it thickens evenly as the sauce heats.
