Step 1

To begin, you need to make a simple sugar syrup. To do this, start by dissolving 1 cup of sugar and 1 cup of water over low heat for a few minutes until the sugar is completely dissolved, then set aside to cool down.

Step 2

Next, you need to steep the butterfly pea flower tea. Simply combine a handful of butterfly pea flowers * and 1 cup boiling water and steep for around 5 minutes. **

Step 3

In a large jug combine the sugar syrup, steeped blue pea flower liquid and the two remaining cups of water and mix.

Step 4

At this point, you can add a few drops of lavender extract (for a soothing lavender taste), if wanted.

Step 5

At this point what you have is a deep blue butterfly pea flower tea. The moment you squeeze the lemon juice into the drink, the colour turns purple. I like to give everyone lemon halves to squeeze the lemon in themselves. However, you can also pre-squeeze the lemon juice and let everyone pour in some lemon juice and stir the drink for the full magical effect.

Step 6

To make the slushies, the first step is to steep the butterfly pea flower tea as mentioned above, pour into ice-cube trays *** and then leave to freeze.

Step 7

Then you need to prepare the lemonade syrup. Unlike above, the lemon will be mixed directly into the syrup for the slushie. Simply follow the directions above the make the sugar syrup, including the lemon juice ****

Step 8

When you want to serve the colour-changing slushies, simply use a food processor to crush the ice (or an ice-crusher). Keep some ice chunks larger and some smaller *****

Step 9

Fill your glasses with the blue ice, pour some lemon syrup into each glass and then top up with water or sparkling water and mix. Voila!
