Sam Buckley's stunning oyster dish is served with bright pink pickled rhubarb and a glossy oyster emulsion. The rhubarb takes at least 2 weeks to pickle, but will last for months so it's worth making a jar full.
Begin by pickling the rhubarb, as it needs at least 2 weeks in order for the maceration to truly take hold. Finely slice the rhubarb, sprinkle it with salt and leave for 1 hour. This draws out excess moisture and opens the pores of the vegetable to maximise penetration of the pickle. Rinse off the salt then pat dry and place in a clean jar
Place the vinegar, sugar and water in a pan with a pinch of salt and bring to the boil. Stir to dissolve the sugar, leave to cool slightly then pour over the rhubarb. Close the lid and store in a cool dark place. Leave to pickle for at least 2 weeks
To make the oyster cream, place the shucked oysters into a jug with the egg white and use a stick blender to blend into a smooth paste. With the hand blender still running, slowly add the oil in a thin stream to produce a glossy emulsion. If the mixture begins to split, add a splash of cold water to bring it back again. Taste and season with salt and lemon juice (if you want a little acidity)
Steam the whole oysters in their shells for around 7 minutes and immediately plunge into ice-cold water to halt the cooking process. Shuck, move gently from the shell and place in the fridge. Keep the curved side of the shells
To serve, spoon some of the emulsion into the base of each oyster shell and top with a steamed oyster. Decorate with pickled rhubarb slices and red shiso cress
