1. To prepare the oysters, carefully open, or shuck, them (visit waitrose.com/howto for a video clip that shows you how to do it). Then run a knife underneath the flesh of the oysters to detach them from the shells. Leave the oysters in the shells and place them on a bed of ice in a dish or platter.
2. To make the shallot dressing, mix together the remaining ingredients in a small bowl. Spoon a little dressing over each oyster and serve immediately. Place any remaining dressing in a small serving pot to serve along side. Serve with a wedge of lemon, if you like.
