Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef kidney
- Forms the main body of the stew and becomes tender with gentle simmering.
- Flour
- Browns with the butter and thickens the liquid into a savoury sauce.
- Butter
- Carries the browning of the onion and kidney and adds richness.
- Onion
- Adds sweetness and savoury depth as it browns in the butter.
- Madeira wine
- Adds acidity and aroma that brighten the rich sauce.
The step that matters
Dust the kidney with flour and stir until the flour is brown. Browning the flour in the fat develops nutty, toasted flavour and gives the sauce colour. Stopping too early leaves a raw floury taste, while burning makes it bitter.
