Lemon posset top tips

  • Make sure you buy unwaxed lemons
  • Rub lemons on the kitchen worktop before you begin to get the most juice from them
  • Zest before juicing 
  • When zesting rub the grater on the lemon as opposed to the lemon on the grater
  • When you're heating the double cream, watch it like a hawk and stir continuously otherwise it will boil over
  • Let the cream and sugar cool slightly before adding the lemon juice so it doesn't curdle
  • Pour the mixture into a glass jug and then transfer to the dish you are using to avoid spillage
  • Lemon possets can be frozen. Defrost in the fridge for a few hours before serving.
