Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kidneys
- Provide the main meat, which becomes tender through long stewing.
- Butter
- Adds fat and richness, carrying flavour through the stew.
- All-purpose flour
- Thickens the butter and liquid into a smooth, body-giving sauce.
- Sweet cream
- Adds richness and a creamy texture to the stew.
- Reserved kidney broth
- Supplies savoury liquid that carries the stew's flavour.
The step that matters
Add the flour to the butter and stir to combine. Flour must be cooked into the melted butter and stirred smoothly before liquid is added; otherwise it clumps and the sauce stays lumpy and thin-tasting.
“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.
