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

What each ingredient does

Eggplant
Provides the bulk and soft, creamy body once cooked down.
Zucchini
Adds moisture and tender texture as it releases its water into the pot.
Green peppers
Contribute sweet, grassy flavor and a softened vegetable texture.
Onions
Build sweetness and savory depth as they soften and brown slightly.
Canned tomatoes
Supply acidity and liquid that form the stewing sauce.
Garlic
Adds pungent aroma that mellows and sweetens during gentle cooking.

The step that matters

Saute about 5 minutes, then simmer gently. Adding the tomatoes too early or boiling hard can leave the vegetables mushy or watery. Cooking the vegetables briefly first lets some moisture evaporate and keeps their flavors concentrated before the long, low simmer.

Fit is the average pairing score against garlic, eggplant, pepper, oregano, basil, parsley, tomato. 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).
