Place flowers and boiling water in a jug and seep for 30 minutes.
Drain flowers, and freeze blue water into ice cubes.
Freeze 2 cups regular water into ice cubes.
Once frozen, blend blue ice cubes in a high speed blender. Leave a few larger chunks in there for some texture.
Repeat with the regular ice.
Place blue ice and white ice into separate containers and store in the freezer until you are ready to build the drinks.
Stack tall glasses half way with regular ice. Top with butterfly pea ice.
Add 1 tablespoon citrus of your choice into each glass. This measurement doesn’t have to be exact, you can add a little more if you like.
Add a little more butterfly pea ice on top, then top with your favourite sparkling beverage and stir.
Garnish and enjoy!
