Why it works: Sweet potato and chickpea share more aroma than cooks usually use. They rank in the top 2% of all ingredient pairs, and 48 recipes mention both. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
The recipe
Ingredients
Directions
Prepare the sweet potatoes
Bring 2 inches of water to a boil in a large saucepan fitted with a steamer basket.
Add sweet potatoes, cover, and steam until tender, about 10 minutes.
Set aside and keep warm until needed.
Make the curry
Heat oil in a large, heavy pot over medium heat.
Add onion, ginger, garlic, scallions, red peppers, 1/2 teaspoon salt, and curry powder.
Stir, cover, and cook 3 to 5 minutes.
Stir in chickpeas (with liquid) and simmer, uncovered, 5 minutes.
Add vinegar and remaining 1/2 teaspoon salt.
Stir in sweet potatoes.
Over low heat, gently stir the mixture about 2 minutes to allow sweet potatoes to release some of their starch. Be careful not to break them up completely.
Add cilantro and stir to blend.
Serve hot.

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 and body of the curry; their starch slightly thickens the sauce as they are stirred.
- Chickpeas
- Add substance and a firm, hearty texture that holds up to simmering.
- Onion
- Softens and sweetens as it cooks, forming the flavor base of the curry.
- Curry powder
- Supplies the warm, aromatic spice blend that defines the dish's flavor.
- Red bell peppers
- Contribute sweetness and color, and soften into the sauce as they cook.
- Cider vinegar
- Adds acidity that brightens the rich, spiced flavors.
The step that matters
Stirring in the sweet potatoes gently. Stirring gently for about 2 minutes releases some starch from the potato surfaces, which helps thicken the sauce. Stirring too hard breaks the potatoes apart into mush, so they keep their shape while the sauce thickens.

Fit is the average pairing score against sweet potato, olive, ginger, garlic, pepper, chickpea, cider. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
