Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kidneys
- Form the main body of the dish, becoming tender as they stew.
- Flour
- Coats the slices and thickens the cooking liquid into a sauce.
- Butter
- Adds richness and fat that carries flavour and helps the slices brown lightly.
- Claret
- Adds acidity and wine flavour that gives the sauce depth.
The step that matters
Stewing the kidneys gently. Kidneys turn tough and rubbery if overcooked. Keeping the heat low and the stewing time measured keeps the slices tender.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
