Spring and summer are on the way, which means it's time for lighter flavours and more refreshing drinks. Anna Jones has the perfect recipe for the season - her Blueberry and Mint Lemonade. You'll need unwaxed lemons, blueberries, mint, agave syrup and sparking or still water. Blitz it up, serve over ice and you'll have a delicious, homemade spring and summer sipper that's packed with vitamins!
