Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheep's heart
- Provides the main meat, which becomes tender after boiling and mincing.
- Sheep's lights
- Adds bulk and a soft, tender texture to the minced mixture.
- Butter
- Carries the flour browning and adds richness to the sauce.
- Flour
- Browned in the butter to thicken the liquid and add a toasty flavour.
- Onion
- Adds savoury sweetness and aroma as it softens in the simmering liquid.
The step that matters
Browning the flour in the butter. Flour must be cooked until lightly browned in fat before liquid is added. Stirring it constantly prevents scorching and lumps, and the cooked starch thickens the sauce smoothly while giving a nutty flavour.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, pepper, sauce):
