Why it works: Butter and parsley are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 28,563 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Eggs Stuffed with Anchovies
Ingredients
Directions
Prepare the eggs
Boil the eggs until hard, then place them in cold water and remove the shells.
Cut the eggs in half lengthwise and arrange them on a flat dish.
Make the anchovy filling
Wash the anchovies, remove the head and backbone, and pound them finely in a mortar or chop as finely as possible.
Add the yolks of the hard-boiled eggs and the butter to the anchovy paste, and mix until smooth.
Fill the half egg whites with the anchovy mixture.
Garnish with parsley.
Serve cold.
Alternative hot version
Alternatively, keep the egg whites warm while adding a whole raw egg and enough fine white crumbs to the anchovy paste to thicken it.
Fill the warm half whites with this mixture.
Serve hot, with or without an anchovy sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Their yolks blend with butter and anchovy to form a creamy, smooth filling.
- Anchovies
- Provide the salty, savoury flavour that defines the filling.
- Butter
- Adds richness and helps the yolk and anchovy mixture become smooth.
- Whole raw egg
- In the hot version, its proteins set when heated, helping thicken the filling.
- Fine white crumbs
- In the hot version, they absorb liquid and thicken the anchovy paste.
The step that matters
Thickening the hot filling with raw egg and crumbs. Raw egg proteins set when heated and crumbs absorb moisture, so the mixture thickens. If the egg whites are not kept warm or the filling is too wet, it may stay loose or not set properly.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter):
- Nutmegfits about as well
- Parsleythe original
- Capersfits about as well
- Tarragonfits less well
Fit is the average pairing score against egg, butter. Candidates are from the same food group and used in at least 100 recipes.
