Soft drink alternative

I've been trying to find an alternative to Coca Cola or beer for summer afternoons, and I think I may have found my solution.

This is iced Rooibos tea, with ginger and lemon. It's delicious! I made it without measuring, but here's roughly what i did.

1. Peel and dice about 10 grams of fresh ginger root. Boil in a covered pot in two litres of water for 2 mins.
2. Turn off heat and add a tablespoon of loose leaf rooibos (red) tea, the juice of 1 lemon and raw sugar to taste.
3. Chill in fridge.
4. Serve with ice (if you havent lost the ice tray over the winter) and fresh mint.
   Enjoy!
