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

What each ingredient does

Leg of lamb
Provides the main meat, which browns and becomes tender as it roasts.
Coarse sea salt
Seasons the surface of the meat and helps form a savoury crust.
Mint sauce
Adds a sharp, acidic contrast that balances the rich roasted lamb.

The step that matters

Moving the lamb closer to the fire. Moving the meat closer only near the end lets the surface brown through the Maillard reaction without overcooking the interior. Moving it too early can dry out or burn the outside before the centre is done.

Swap the mint

How well each one fits the dish's main ingredients (lamb, sauce, peas, spinach, cauliflower):

  1. Capersfits better
  2. Garlicfits better
  3. Turmericfits better
  4. Mintthe original

Fit is the average pairing score against lamb, sauce, peas, spinach, cauliflower. Candidates are from the same food group and used in at least 100 recipes.
