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

What each ingredient does

Sweet potatoes
Provide the bulk of the dish, turning soft and starchy as they cook through.
Butter
Carries the curry powder and helps the potato surfaces brown.
Curry powder
Supplies the spiced aroma and flavour that defines the dish.
Soup stock
Cooks the potatoes gently and forms the liquid base of the sauce.

The step that matters

Browning the potatoes in butter. Browning over medium heat with the curry powder toasts the spices and caramelises the potato surfaces, building flavour. Too high a heat can scorch the butter and spices before the potatoes cook through.

Swap the sweet potato

How well each one fits the dish's main ingredients (butter, pepper):

  1. Capsicumfits better
  2. Potatofits better
  3. Carrotfits better
  4. Sweet potatothe original

Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
