I love this drink - so quick to make, and healthy too. :D
2 tablespoons lemon or lime juice (I use the Select brand from Woolworths)
1/2 teaspoon bi-carbonate soda
500 ml of water.
In a tall glass or a small jug, combine 500 mls of water and the juice. Just before you are ready to serve, add the bi-carbonate soda and sterve really well. Enjoy!
