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

What each ingredient does

Italian bread
Soaks up the stock and tomato, thickening the soup into a hearty body.
Olive oil
Carries the flavor of the aromatics and adds richness to the finished soup.
Plum tomatoes
Provide the main body, acidity and sweetness as they break down in the simmer.
Garlic
Adds pungent aroma that mellows and sweetens as it cooks in the oil.
Beef stock
Supplies the liquid and savory depth that the bread and tomatoes absorb.
Fresh basil
Adds a fresh, aromatic herbal note that brightens the cooked tomatoes.

The step that matters

Golden garlic. Garlic turns bitter and acrid if it burns in hot oil, so cook it gently with stirring until just golden before adding liquid.
