Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Their fat and emulsifying lecithin give the filling a smooth, rich, creamy body.
- Butter
- Adds fat that makes the filling soft, spreadable and rich in mouthfeel.
- Curry powder
- Provides the warm, spiced aroma that defines the flavour of the filling.
- Fine breadcrumbs
- Absorb moisture and fat, helping the filling hold together and firm up slightly.
- Tarragon vinegar
- Adds a light acidity that brightens the rich yolk and butter mixture.
The step that matters
Pounding until smooth. Pounding breaks down the cooked yolks and softens the butter so they blend into an even paste. Lumps left in the filling will spread unevenly and make the sandwich texture grainy rather than creamy.
