What each ingredient does

Boston brown bread: Provides the soft, slightly sweet base that holds the cress between its slices.
Melted butter: Adds richness and moisture, and helps the mustard and lemon juice coat the cress.
Lemon juice: Adds acidity that brightens the flavour and cuts the richness of the butter.
