Why it works: Egg and anchovy match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and 2,268 recipes mention both. Both carry 1-octen-3-ol, which smells mushroom, earthy. 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 eggs
Cut the hard-boiled eggs in half.
Remove the yolks.
Rub the yolks through a sieve.
Trim the tips of the egg whites to make them stand evenly.
Make the filling
Chop half of the tongue finely and mix it with half of the egg yolks.
Cut six rounds of buttered toast, matching the size of the egg halves, and top with the tongue and yolk mixture.
Finely chop the remaining tongue, gherkins, olives, and anchovies, then mix with a few drops of oil and lemon juice.
Add chopped parsley, capers, and a pinch of pepper to the mixture.
Fill the egg white halves with the mixture, piling it high but loosely.
Assemble and serve
Place each filled egg half on a round piece of prepared toast and serve cold as a savory dish or for breakfast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Provide the white shells for the filling and the yolks that form the creamy base.
- Tongue
- Adds savory, meaty flavor and a firm texture to the filling.
- Anchovy fillets
- Add a salty, savory depth to the mixture.
- Gherkins
- Add tangy acidity and crunch to the filling.
- Spanish olives
- Add salty, briny flavor and a bit of texture to the filling.
The step that matters
Fill the egg white halves loosely. Piling the mixture high but loosely keeps the filling light and airy rather than dense and packed. Packing it tightly makes the texture heavy and greasy, while a loose mound holds its shape and gives a softer bite.

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