Cook the kidneys
In a stew-pan, melt the butter over a brisk fire.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheep kidneys
- Form the main meat, giving the dish its firm, tender texture once cooked.
- Butter
- Provides fat for cooking the kidneys and carries a rich, savoury flavour.
- Champagne
- Adds acidity and aroma, and its reduction concentrates flavour into the sauce.
The step that matters
Keep the sauce from boiling. Once the kidneys are in the sauce, boiling would toughen the proteins and make them rubbery. Keeping the sauce just below a simmer lets the kidneys warm through while staying 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.
