Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Water cress
- Adds a fresh, peppery flavour and bulk to the filling.
- Hard boiled eggs
- Provide the soft, creamy body that binds the filling.
- Bread
- Forms the structure that holds the filling together.
- Butter
- Adds fat and richness and helps keep the bread from soaking up moisture.
- Lemon juice
- Adds acidity that brightens the flavour of the filling.
The step that matters
Dry the watercress thoroughly. Excess water from wet leaves seeps into the bread and makes the sandwich soggy. Pressing the leaves dry in a cloth keeps the filling moist without making the bread wet.
