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

What each ingredient does

Black beans: Provide the main body and protein of the dish, holding their shape when heated through.
Sweet potatoes: Add sweetness and a soft, starchy texture as they cook down in the pot.
Leeks: Contribute a mild onion-like sweetness and soften into the vegetable base.
Dried red peppers: Supply heat and a smoky, pungent aroma when bloomed in the cooking liquid.
Lime juice: Adds acidity that brightens the flavor and balances the sweetness of the vegetables.

The step that matters

Blooming the dried red peppers and spices. Cooking the chili, cumin and thyme briefly in liquid releases their fat-soluble and aromatic compounds, and keeping the heat low prevents scorching and bitterness.
