Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Yolks form the creamy base of the spread, while the whites add mild texture as garnish.
- Butter
- Adds fat and richness, binding the pounded yolks into a smooth, spreadable paste.
- Anchovy essence
- Provides a salty, savoury flavour that seasons the yolk and butter mixture.
- Gluten coffee biscuits
- Form the crisp, plain base that carries the topping.
The step that matters
Pass the mixture through a sieve. Sieving breaks up lumps in the pounded yolk and butter, producing a smooth, even paste that spreads evenly on the biscuits instead of clumping.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter, anchovy, coffee, biscuit):
- Capersfits better
- Nutmegfits better
- Parsleythe original
- Cinnamonfits about as well
Fit is the average pairing score against egg, butter, anchovy, coffee, biscuit. Candidates are from the same food group and used in at least 100 recipes.
