In a high-speed blender jar, add sliced peaches, sugar, lemon juice and 1 cup water. Blend everything together until smooth.
Transfer the prepared peach mixture into a small sauce pan, heat and bring it to a boil. Once the juice boils, simmer for 30 seconds and then take it off the heat, our homemade peach syrup is ready.
Transfer the syrup in a pitcher. NOTE : As my peach syrup was smooth and free from any pulp or peel bits, I have skipped the step of straining it. If your mixture isn't smooth, then, strain the nectar using a fine mesh strainer.
In a medium sauce pan, add the remaining water and bring it to a point when it starts to bubble.
Add tea leaves and bring to boil, simmer for 2 minutes only. Beyond this time, the tea can get bitter. However, if you want the tea to be stronger, add more tea and brew for another 2 minutes.
Once brewed, switch off the heat and let it rest for 5-6 minutes. Strain out the tea leaves and add it to the pitcher with syrup, stir and refrigerate.
Put few ice cubes along with thin peach slices and few fresh mint leaves into serving glasses, stir and pour the iced tea mixture and serve!
