Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Lamb
Provides the main protein, which firms up and browns as it roasts.
Potatoes
Their starch softens when boiled or steamed, giving a soft, fluffy texture.
Peas
Soften when cooked and add a mild, natural sweetness to the plate.
Mint sauce
Vinegar adds acidity and sugar adds sweetness, cutting through the richness of the lamb.

The step that matters

Roasting the lamb to your preference. Meat keeps cooking from residual heat after leaving the oven, so it should come out a little before the target doneness. Overcooking dries the muscle fibres and toughens the meat.
