  • In a large heatproof bowl, add the erythritol, lemon juice and zest, and butter.
  • Set the bowl over a saucepan of simmering water.
  • When the butter has melted, remove the bowl from the saucepan and ensure that the liquid isn’t too hot. If you can keep your finger submerged for a few seconds then it is cool enough.
  • In a separate bowl, whisk together the eggs and yolks.
  • Pour the eggs into the lemon mixture while whisking, until all ingredients are combined.
  • Place the mixture back over the saucepan of simmering water and whisk continuously until the mixture thickens.
  • Remove from the heat and continue to whisk for another 10-15 minutes while the curd cools.
  • Pour into a clean jar and place cling film directly onto the curd.
  • Place the jar in the fridge for at least 4 hours to completely chill before enjoying.
