1. Place the Tea leaves in a large heatproof glass pitcher. Use a peeler to strip the peel from a lemon or orange and add it to the pitcher.
2. Pour simmering hot or cold water into the pitcher and let it steep for at least 5 minutes. Strain the tea leaves and discard. Refrigerate the tea until cold.
3. To serve, fill iced tea glasses with ice and pour the tea over the ice. Sweeten with simple syrup, if desired.
