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

What each ingredient does

Cold leg of mutton
Provides the main meat filling, giving savoury flavour and body to the scallop.
Mashed potatoes
Forms a soft topping that covers the meat and helps it stay moist during cooking.
Butter
Adds fat for richness in the potato topping and helps it take on golden browning.
Milk
Loosens the mashed potatoes so they spread smoothly over the meat.

The step that matters

Brown in a Dutch oven until golden. Browning depends on surface heat and dryness. If the topping is too wet or the heat too low, it steams rather than browns, leaving a pale, soft crust.
