Boil about 16 cups of water in large pot 2. Add 1 cup tea mix & stir occasionally 3. Add 1 cup of sugar & stir, steep for 20 minutes to ensure strong flavor 4. Strain out the tea or pour out tea liquid into jug (the tea mix sediment should have fallen to the bottom of the pot so if you pour carefully you may not need a strainer) 5. Put jug into fridge until you have that craving for Thai Iced Tea Preparation: Fill a glass with lots of ice, pour in Thai Tea, add a couple of tea spoons of evaporated milk (or half&half) to the top and you are ready to enjoy Thai Iced Tea!!
