Cut the peach into pieces. Put the pieces into the blender.
Add the lemon juice, tea and simple syrup. Add more if you prefer a sweeter taste. Blend all ingredients together.
Strain into a jug with plenty of ice cubes or crushed ice.
Notes
Use ripe peaches: They blend more easily and give better sweetness. Strain well: Use a fine mesh strainer to remove pulp and skins. Chill your tea: Let tea cool fully before blending for best results. Taste as you go: Adjust syrup or lemon juice to your sweetness preference.
