Why it works: Fennel and chickpea share more aroma than cooks usually use. They rank in the top 4% of all ingredient pairs, and 39 recipes mention both. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
The recipe
Ingredients
Contains: wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the base
Heat the oven to 180°C / gas mark 4.
Put the onion and fennel in a large pan, add three tablespoons of oil and sauté over medium heat for four minutes.
Add the carrot and celery, and soften, stirring occasionally, for four minutes.
Add the tomato purée, stir for a minute, then add the wine and let it bubble for a minute or two.
Add the tomatoes, herbs, sugar and stock, and season.
Bring to a boil, cover and simmer gently for 30 minutes.
Toast the bread and crush the chickpeas
Meanwhile, break the bread into chunks, toss with two tablespoons of oil and some salt, and scatter in a roasting tin.
Bake for 10 minutes, until thoroughly dry, then set aside.
About 10 minutes before you want to serve, put the chickpeas in a bowl and crush them a little with a potato masher or the end of a rolling pin; you want some to be left whole.
Finish and serve
Add the chickpeas to the soup and simmer for five minutes.
Next add the toasted bread, stir and cook for another five minutes.
Taste the soup and add salt and pepper liberally.
Ladle the hot soup into bowls.
Spoon some pesto in the centre, drizzle with plenty of olive oil and finish with shredded basil, if you like.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale sourdough bread
- Thickens the soup and soaks up broth, giving it a hearty, bread-based body.
- Chickpeas
- Add body and texture when partly crushed, while whole pieces keep some bite.
- Tinned plum tomatoes
- Provide acidity and liquid that form the base of the soup.
- Olive oil
- Carries flavour from the aromatics and adds richness to the soup and bread.
- White wine
- Adds acidity and aroma as it bubbles and reduces into the base.
- Onion
- Softened in oil, it builds sweetness and savoury depth as the base flavour.
The step that matters
Drying the bread before adding it to the soup. Baking the bread until thoroughly dry lets it toast and hold its shape, so it thickens the soup without turning soggy and disintegrating into it.

Fit is the average pairing score against onion, fennel, olive, carrot, celery, tomato, white wine. 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).
