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

What each ingredient does

Portobello mushrooms: Provide meaty bulk and absorb the spiced liquid as they soften.
Red kidney beans: Add body and substance, thickening the chili as they break down slightly.
Italian plum tomatoes: Supply the liquid base and acidity that carries the spices through the pot.
Onions: Build sweetness and savory depth as they soften in the oil.
Garlic: Adds pungent aroma that mellows and sweetens during gentle cooking.

The step that matters

Sautéing the mushrooms until softened. Mushrooms release a lot of water as they cook. Cooking until that liquid evaporates lets them brown slightly, concentrating flavor instead of leaving the chili watery and bland.
