SPECIAL TOOLS

      If making into bars

      Instructions

      CONVENTIONAL METHOD

      • If making into bars please use the technique highlighted in the blog post.
      • Preheat oven to 180℃.
      • Beat together butter and sweetener until light and fluffy.
      • Add egg yolk, whole egg, lemon juice, and vanilla. Beat for 1 minute.
      • Mix in dry ingredients and blend well.
      • Split dough in half and roll out each half of dough between 2 sheets of baking paper to approximately 2mm thick and approximately the size of the baking tray you are going to use to assemble the slice. I use a 28cm x 21cm slice tin. See images for tips.
      • Lift pastry filled paper and place onto a large baking tray.
      • Bake for about 10-12 minutes until lightly golden. Biscuit will still be soft. Allow to cool on tray for 5 minutes then move to wire rack to cool completely. Biscuits will continue to crisp over a couple of hours.
      • Move 1 sheet of pastry to a baking paper lined tin (28x21cm) and reserve.

      VANILLA CUSTARD

      • Add cream and vanilla to a small saucepan. Whisking mixture over medium heat until a low simmer and remove from heat.
      • In a separate bowl whisk together eggs, sweetener, xanthan, and gelatin. Whisk through cream mix and return to heat and continue whisking until custard thickens and coats the back of a spoon.
      • Remove from heat and allow to cool.
      • Fold through 1/3 of the prepared lemon curd.
      • Pour custard onto prepared pastry in baking tin. Top with second pastry sheet. Cover and refrigerate for 3-4 hours until custard has set.
      • Top vanilla slice with extra lemon curd and coconut flakes.
      • Cut and serve.
