Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of lamb
- Forms the main body of the dish and carries most of the flavour and texture.
- Butter
- Adds richness and fat to the sauce, giving it a smooth, silky mouthfeel.
The step that matters
Boil the lamb gently. Gentle simmering keeps the meat tender and prevents the outer proteins from tightening and toughening. A hard, rapid boil can make the meat stringy and cause it to break apart.
Swap the parsley
How well each one fits the dish's main ingredients (lamb, butter, sauce):
- Capersfits about as well
- Parsleythe original
- Garlicfits about as well
- Cinnamonfits less well
Fit is the average pairing score against lamb, butter, sauce. Candidates are from the same food group and used in at least 100 recipes.
