  1. For the tartare: place all the ingredients in a blender and whizz until smooth. Transfer into a squeezy bottle or piping bag.
  2. For the batter: place the flour in a bowl. Add the remaining ingredients and whisk until smooth.
  3. For the fritters: place the oysters in the flour. Coat evenly, then dust off any excess flour.
  4. Dip each oyster in the batter, then tightly wrap the spiralized potato around to make a fritter.
  5. Heat the deep fat fryer to 165–170°c. Fry the fritters in the oil until golden and crisp. Remove and pat off excess oil with a paper towel.
  6. To serve: squeeze some of the tartare onto plates and place each fritter on top. Then use the tartare to fill in any gaps in the fritters.
