Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tender, cold roast leg of lamb
- Provides the savoury meat filling that forms the bulk of each sandwich.
- Fresh bread
- Gives structure and holds the filling together in the sandwich.
- Butter
- Adds richness and a fat layer that helps limit moisture soaking into the bread.
- Thick mint sauce
- Adds acidity, sweetness and bright mint aroma that contrast with the rich lamb.
