The vibrant blue colour is achieved by using Blue Butterfly Pea Flowers. A great and totally natural food colouring!
Ingredients
- Sponge cake (I made a vanilla sponge using the Fielders Sponge Cake Recipe and added the seeds from one vanilla pod to the mixture)
- 10 Blue Butterfly Pea Flowers (ground)
- 2 cups icing sugar
- 1 1/2 cups water
- 2 tablespoons cornflour
- 1 vanilla pod (seeds only needed)
- 2 cups desiccated coconut (approximately)
- Whipped cream to fill and serve with the lamingtons
Method
- Start by removing the calix (green part) from each flower. You will need approximately 10 flowers. Using a mortar and pestle, grind the flowers into a powder. This may take a few minutes. Sieve out the larger pieces.
- Next, add the Blue Butterfly Pea powder and water to a saucepan and bring to a boil.
- Once boiling, reduce the heat and add the icing sugar and vanilla seeds. Allow to simmer for a few minutes.
- Mix the cornflour with 1-2 tablespoons of cold water. You need to be able to pour the mixture.
- Stirring rapidly, add the cornflour mixture to the saucepan and continue stirring until it thickens. Ideally you want the consistency to be that of a runny gravy. Add a little more cornflour mixed with cold water if needed.
- Once the cornflour has been cooked through and the mixture is clear, remove it from the heat and allow to cool completely.
- Cut your sponge into squares and dip each square into the glaze ensuring all of the sponge is covered. Lift out and drain off the excess glaze.
- Quickly place the sponge into the coconut and roll until well covered.
- Place on a rack and allow to set.
- Repeat until all sponge pieces are completed.
- Once set, take a sharp knife and cut a “v” shape from the top of the sponge.
- Pipe cream into the gap, then place the “v” shape of the sponge on top.
- Refrigerate until ready to serve.
