Directions

Prepare

  1. Wash the watercress thoroughly and dry it in a cloth, pressing out all moisture.

Assemble and serve

  1. Slice the stale loaf into thin slices for two dozen sandwiches.

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

What each ingredient does

Watercress (in the method)
Provides a fresh, peppery flavour and a moist filling that must be dried well.
Hard-boiled eggs
Add body and richness to the filling, binding it into a soft spread.
Fresh butter
Adds fat and richness and keeps the bread from soaking up the moisture of the filling.
Stale loaf of bread
Stale bread is firmer, so thin slices hold the filling without tearing or going soggy.

The step that matters

Drying the watercress. Any water left on the cress will soften the bread and make the filling runny. Pressing it dry in a cloth keeps the sandwiches firm and stops the slices from becoming soggy.
