Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Tomato and Bread Soup
Ingredients
Directions
Prepare the bread
Preheat oven to 350°F. Place bread cubes on a baking sheet and toast until edges are lightly brown, about 8–10 min.
Make the soup
Heat olive oil in a 5‑quart pot over medium heat, add onions and cook for 3–4 min or until they begin to soften.
Add the garlic and crushed red pepper and continue to cook, stirring, for an additional 5 minutes or until the garlic becomes golden.
Add pepperoncini, tomatoes, beef stock and toasted bread and bring to a boil.
Reduce to a simmer, add basil and cook, covered, 30–40 minutes, stirring occasionally.
Serve
Season to taste with salt and pepper. Ladle into soup bowls and drizzle with olive oil, garnish with crumbled gorgonzola.

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.
Swap the plum
