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

What each ingredient does

Potatoes: Break down partly as they simmer, thickening the sauce and giving it body.
Chickpeas: Add firm, starchy bulk that holds its shape and makes the curry filling.
Tomato paste: Concentrates savory depth and gives the sauce a richer color and body.
Brown sugar: Balances the acidity of the tomato and lemon with a touch of sweetness.
Apple juice: Provides the liquid for simmering and a gentle fruity sweetness.

The step that matters

Simmer uncovered for 30 minutes. Simmering uncovered lets liquid evaporate so the sauce thickens, while stirring prevents the starchy potatoes from sticking and scorching on the bottom of the pot.
