Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal kidney
- Provides the main meat, which turns tender when fried briefly and firm when overcooked.
- Butter
- Browns the kidney and adds richness to the frying surface.
- Mushrooms
- Add earthy flavour and body to the sauce.
- Stock or consommé
- Forms the liquid base of the sauce.
- Flour
- Thickens the stock so the sauce coats the kidney.
- Sherry
- Adds acidity and depth of flavour to the sauce.
The step that matters
Fry the kidney without overcooking. Kidney becomes tough and dry when cooked too long, because its proteins tighten under sustained high heat. A short, hot fry browns the outside while keeping the inside tender.
