MUDDLE: Add the raspberries and lime juice to a pint sized mason jar and use a cocktail muddler (or the back of a spoon!) to gently press the raspberries into the lime juice.
MIX: Add the tart cherry and pomegranate juices to the jar. Put the lid on the jar and add a few ice cubes – shake to combine and chill the juices. Remove the lid, then top the drink off with sparkling water. Garnish with a few extra raspberries and a lime slice before enjoying!
