Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kidneys
- Main protein; a brief, hot fry gives a browned surface and a tender interior.
- Champagne or claret
- Adds acidity and wine aroma to the sauce, balancing its richness.
- Shallots
- Add a mild, sweet onion aroma that deepens as the sauce cooks.
- Small onions
- Add sweetness and soft texture once sautéed until tender.
- Fresh butter
- Adds fat and rich flavour, and helps the onions brown as they sauté.
The step that matters
Frying the kidneys for 6 minutes. Kidneys turn tough and rubbery when overcooked, because their proteins tighten under prolonged high heat. Frying them briefly and removing them promptly keeps the inside tender.
