Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Anchovies
- Provide the main salty, savoury flavour that defines the dish.
- Egg yolk
- Thickens the mixture as it heats, giving it a creamy, spreadable texture.
- Butter
- Adds richness and fat, helping the shallot brown and carrying flavour.
- Shallot
- Adds mild aromatic sweetness and depth when fried until lightly browned.
The step that matters
Stir the mixture over low heat until it thickens. Egg yolk thickens by gentle heat. If the heat is too high, the yolk can scramble into lumps instead of forming a smooth, creamy topping.
Swap the shallot
How well each one fits the dish's main ingredients (butter, egg, parsley, pepper):
