Butterfly Pea Flower (in syrup, extract, spirit infusion, ice cube, or tea form) is a trendily instagrammable cocktail ingredient that has risen to prominence in the last few years. It doesn’t really taste like much, but it has a beautiful color that changes in reaction to the pH of any drink it’s added to, much the same way a litmus strip does.

To use a butterfly pea flower ingredient to its fullest, then, you want to make sure that it only comes into contact with acidic ingredients at time of serving. Options include adding the butterfly flower ingredient as a float to an acidic drink like a lemonade, freezing it into ice cubes that change color as they melt, or mixing up a basic drink that includes the blue extract and then adding an acid to it. The effect works just as well in mocktails as in cocktails!
