Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Breast of mutton or lamb
- Provides the main body of the dish, becoming tender during slow simmering.
- Veal forcemeat
- Adds moisture and richness inside the rolled meat as it cooks.
- Onion
- Adds savoury sweetness and aroma to the stock and gravy.
- Stock
- Forms the liquid base that becomes the gravy, carrying flavour from the bones.
- Flour
- Thickens the cooking liquid into a smooth, coating gravy.
- Dripping
- Fat that browns the outside of the rolled meat during quick frying.
The step that matters
Thicken the gravy with the flour. Flour clumps if added raw to hot liquid. Mix it smoothly first, then let the gravy boil so the starch swells and thickens it evenly.
Swap the onion
How well each one fits the dish's main ingredients (mutton, veal, pepper, flour):
