Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Watercress (in the method)
Adds a fresh, peppery flavour and moist, leafy bulk to the filling.
Hard-boiled eggs
Provide a soft, creamy body that binds the watercress filling.
Fresh butter
Coats the bread, adding richness and keeping the filling from soaking into the slices.
Stale loaf of bread
Stale bread is firmer and holds its shape when thinly sliced and pressed.

The step that matters

Press out all moisture from the watercress. Excess water from wet watercress soaks into the bread and makes the sandwiches soggy. Drying it well keeps the slices firm and the filling crisp-fresh.
