Our Thai Tea mix is from the Cha Thai Tea Mix bag. We reduced the amount of sugar that they suggested, but you can definitely add more if you like your Thai Iced Tea to be sweeter. The finished and brewed Thai tea mix keeps well in the fridge. Brew the tea, strain, and then chill, storing in the fridge until you are ready to serve. This can be done several days ahead of time. The brewed thai tea lasts about 10 days in the fridge (without the half and half).
Bring water to boil and add the thai tea mix. Add sugar and gently stir to completely dissolve sugar. Gently boil tea for about 3 minutes. Remove from heat.
Allow tea to steep for at least 30 minutes and allow it to cool. The more concentrated the tea flavor, the better the Thai tea tastes.
Strain the Thai tea and aside to cool (we prefer to strain through a traditional re-useable cloth filter to remove any sediment). You can make this ahead of time and have the Thai tea chilling in the fridge. Completely chill before serving.
Fill glasses with ice and pour in Thai tea leaving enough room to fill in your half and half (or other creamer). For an 8 oz. glass we like to add about 2-3 tablespoons of half and half for a creamier flavor.
