Blue Spirulina is a vibrant blue pigment derived from blue-green algae.
To create beautiful coloured layers in drinks, dissolve blue spirulina
powder in warm water and pour it as the first layer in your glass. Then,
slowly pour a contrasting drink, like oat milk and matcha, over the back
of a spoon to maintain the layers. Using liquids with different densities
helps achieve a striking, multi-layered effect.
