Oyster Canape

Preparation:

Preparation: Cut the slices of bread into discs, then toast them and let them cool. Thoroughly wash the oysters and open them with the appropriate tool. Remove the molluscs and place them in a bowl. Put the butter, slightly softened at room temperature, in a bowl and work it with a wooden spatula to whip it into a cream; add a pinch of salt, a pinch of pepper and the mustard and mix everything thoroughly. Spread the slices of bread with part of this mixture and arrange an oyster in the centre. Add the ketchup to the remaining butter and stir until everything is well blended. Put the mixture in a pastry bag with a star nozzle and decorate the oysters with a string of cream. Arrange the canapés on the serving plate, which you will decorate with lemon slices and parsley, and serve immediately.
