Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb
- Provides the main meat, which becomes tender through gentle cooking in the gravy.
- White forcemeat
- Stuffs the pocket cut from the lamb, adding moisture and richness to the meat.
- Mutton gravy
- Braises the lamb and forms the base of the sauce, adding savoury depth and moisture.
- Madeira wine
- Adds sweetness and aroma to the gravy as it reduces.
- Oysters
- Adds a briny, savoury flavour to the gravy.
- Flour
- Thickens the gravy when rolled with butter, giving it body.
The step that matters
Thicken the gravy with butter rolled in flour. Adding the flour-butter mixture to hot liquid lets the starch disperse and swell evenly. Added to cold or unmixed, it clumps and leaves a grainy, lumpy sauce.
