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

What each ingredient does

Onions: Soften and brown to build a sweet, savory base for the dish.
Garlic: Adds pungent aroma that mellows as it cooks in the oil.
Plum tomatoes: Provide moisture and acidity that combine with the vegetables into a sauce.
Black olives: Add salty, briny flavor and fat-rich richness to the vegetables.
Fennel bulb: Contributes mild anise aroma and becomes tender and sweet when simmered.
Mushrooms: Release moisture and savory depth as they cook down.

The step that matters

Simmer until just tender. Covering and simmering on reduced heat softens dense vegetables like fennel and carrot gently. Overcooking turns them mushy and dulls their color, while undercooking leaves them fibrous.
