Water Cress Sandwiches
two dozen sandwichesIngredients
Directions
Prepare the filling
Wash the watercress well and dry it in a cloth, pressing out all moisture.
Remove the stems from the watercress and cut it into small pieces.
Mix the chopped hard-boiled eggs with the watercress, seasoning with salt and pepper.
Assemble and cut
Slice the stale loaf of bread thinly for two dozen sandwiches.
Spread butter on each slice of bread, then place the cress mixture between the slices.
Sprinkle a little lemon juice on the cress, press the slices together firmly.
Cut the sandwiches into small squares, removing the crusts.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Watercress
- Provides the peppery flavour and the green filling that forms the sandwich's body.
- Hard-boiled eggs
- Adds a soft, rich texture and bulk to the filling.
- Fresh butter
- Coats the bread, adding fat and richness and helping keep moisture from soaking in.
- Stale loaf of bread
- Stale bread is firmer and holds thin slices together without crumbling under the filling.
- Lemon juice
- Adds acidity that brightens the cress flavour.
The step that matters
Drying the watercress. Any water left on the cress will soften the bread and make the sandwiches soggy. Pressing it dry in a cloth keeps the slices crisp and holding together.
