This simple magic colour-changing Lemonade is made using butterfly pea flower and turns from blue to purple in front of your very eyes. This magical concoction is sure to impress kids and guest alike! Plus, it uses 100% natural colouring and less than 10 ingredients!
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.
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. **
In a large jug combine the sugar syrup, steeped blue pea flower liquid and the two remaining cups of water and mix.
At this point, you can add a few drops of lavender extract (for a soothing lavender taste), if wanted.
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.
Magic Colour-Changing Slushies:
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.
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 ****
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 *****
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!
* Alternatively, you can use butterfly pea flower tea bags. I'd use between 3-5 for a really rich blue colour.** The longer you steep them, the deeper the colour will get. *** The size/shape of the ice-cube trays doesn't matter, as we are going to crush the ice.**** Depending on how tart you prefer your lemonade, you can add more or less lemon juice. I would suggest between 1-2 lemons.***** Because the smaller ice bits will melt quickly and change colour. However, if you have larger chunks then your drink will be a gorgeous mixture of pink, purple and blue tones.
