Carrot, Apple & Mandarin Sour That’s right, carrot… but its not as scary as you might think. Carrots have a naturally sweet flavour which works fantastically well with that natural sweetness of apple and mandarin. So we wanted to play on this as well as the other aspects of some of the fruits, the sourness. A perfect balance of sweet and sour derived from ingredients which compliment each other for an appley, orangey mouth watering, lip puckering sour.
