This is the world's first produced commercial butterfly pea flower extract. This bright blue concentrated extract from the butterfly pea flower is the perfect and completely unique way to add natural sweetness and colour without watering down your cocktail. Only sugar and water were added to the extract from the intriguing flower, which is native to Thailand and Malaysia.If you want to have some fun, you can add highly acidic ingredients like limes or lemons and, depending on the surrounding light, the colour could well change from blue to purple or pink.
