Put the butterfly pea flowers into a heat proof container or bowl.

Pour the 6 cups of water over the flower petals and cover it with a lid or cling wrap, then let it steep for 10 minutes.

Strain out any remaining flower petals using a fine sieve and pour the liquid into an ice cube tray.

Place in the freezer until frozen solid, usually 2 to 3 hours depending on your freezer temperature setting. Enjoy!
