Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork fat
- Carries the flavour and fat for the roux, helping the flour cook evenly and brown.
- Flour
- Thickens the sauce as it cooks with the fat and water, giving it body.
The step that matters
Cooking the flour until brown. Flour cooked in fat browns gradually, and too little time gives a pale, raw-tasting sauce while too much can scorch and turn bitter. Keep stirring and watch the colour closely.
