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.
- Butter
- Adds fat and richness, and helps the kidneys brown in the pan.
- Champagne
- Adds acidity and aroma, and helps lift flavour from the browned pan.
- Mushroom ketchup
- Adds savoury depth and umami to the sauce.
The step that matters
Browning the kidneys. Searing the minced kidneys in butter before adding liquid builds deeper, savoury flavour through browning. Adding the water and wine too early would steam the meat instead, leaving it pale and less flavourful.
“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.
