Fermentation is so hot right now! Kefir is a fermented milk drink, originating from Caucasus region of Eurasia. After reading about kefir’s many health benefits, particularly for the digestive system – and even as an anxiety-buster – I wanted to try creating an easy and tasty shake.

This choc banana kefir-shake includes simple, classic milkshake flavours, and makes a good breakfast drink, or – being high in protein – as a pre- or post-workout snack. This recipe is really flexible, too – if you love veg in your smoothies, why not add a handful of spinach?
