Method – for the topping

  1. Zest then juice all four lemons (trust me you want to do it in that order)
  2. Place the caster sugar, flour, eggs, half of the zest and 3/4 of the juice into a bowl
  3. Whisk until combined
  4. Pour over the base and bake for 15-20 minutes or until set and golden
  5. Refrigerate for around 2 hours until cold
  6. When cold, in a bowl add the remaining lemon juice to icing sugar 1tsp at a time until its runny and spreads easily but not watery. Mine was a little too thin but at this point I was out of sugar. If it is too watery add more sugar, too thick add more lemon juice, if you run out of lemon juice just use water
  7. Sprinkle the remaining lemon zest over icing
  8. Refrigerate until the icing has firmed up, slice and serve

I used candied lemons as my decoration, if you would like to do the same slice up 2 lemons. Add to a pan equal parts sugar and water and bring to the boil before adding the lemons. Boil for 10-12 minutes try not to stir but keep a close eye on it in case it burns. Then transfer to a wire rack to cool.
