Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shoulder of lamb
- Forms the main body of the dish; its fat and connective tissue keep the meat moist and tender as it cooks.
- Fresh butter
- Adds richness and a smooth, rounded fat to the sauce.
- Lemon juice
- Adds acidity that brightens the rich sauce and lamb.
- Ketchup
- Adds sweetness and tomato acidity to the sauce.
The step that matters
Grill gently until fully cooked and light brown. Lamb shoulder is thick and has connective tissue. High heat can brown the outside and burn it before the centre is cooked, while gentle heat lets the inside cook through and the surface brown evenly.
Swap the lemon
How well each one fits the dish's main ingredients (lamb, pepper, ketchup, butter, tomato, sauce):
- Lemonthe original
- Limefits about as well
- Avocadofits less well
- Grapefits less well
Fit is the average pairing score against lamb, pepper, ketchup, butter, tomato, sauce. Candidates are from the same food group and used in at least 100 recipes.
