Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Anchovies
- Provide the salty, savory flavor that defines the filling.
- Hard-boiled egg
- Its yolk becomes a rich, creamy base for the spread.
- Butter
- Binds the pounded filling and adds richness and moisture to the bread.
The step that matters
Pound until smooth. Thorough pounding breaks the anchovies and yolk into a uniform paste; lumps left behind make the spread uneven and hard to cut cleanly in the sandwich.
