Why it works: Olive and tomato match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 14,164 recipes mention both. Both carry 3-hexenal, which smells apple, fruity. The science ↓
The recipe
Ingredients
Contains: egg, wheat, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the olives
Stone the olives and fill them with a mixture of anchovy paste, reduced tomato juice, and cayenne pepper to taste.
Assemble the croutons
Cut rounds of brown bread about the size of a coin.
Spread the prepared paste thickly over the bread rounds.
Place an olive in the center of each crouton.
Wrap a fillet of anchovy around each olive.
Garnish and serve
Garnish with sprigs of finely picked parsley or coarsely chopped hard-boiled egg whites.
Serve on a folded table napkin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Large queen's olives
- Serve as the central filling and main visible element of each bite.
- Anchovy paste
- Adds a salty, savoury depth to the filling and the bread spread.
- Reduced tomato juice
- Adds concentrated acidity and flavour to the paste, helping it spread thickly.
- Brown bread
- Forms the crisp base that holds the paste and olive.
- Fillets of anchovies
- Wrap the olive, adding a salty, savoury flavour to each bite.
- Hard-boiled eggs
- Provide a mild, creamy garnish that adds texture and contrast.

Fit is the average pairing score against olive, anchovy, tomato, pepper, bread, egg. 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).
