What each ingredient does

Large oysters: Provide the main filling, with a briny, savoury flavour once pounded into the mixture.
Lemon juice: Adds acidity that brightens the oysters and balances their richness.
Thin brown bread: Acts as the sandwich base, holding the oyster filling between its slices.
