Frozen blackberry smoothie
Make this blackberry smoothie part of a festive non-alcoholic drinks menu. It's delightfully sweet and sharp, with banana, stem ginger and pomegranate juice
Fill a tumbler with ice, then pour in the apple juice, cider vinegar, stem ginger syrup and stir. Slowly top up with the sparkling rhubarb soda.
Stir again with a sprig of rosemary and leave it in the drink as the garnish.
