Bring four cups water to a rapid bowl in a teapot or saucepan. Remove from
heat and add tea bags. Allow tea bags to steep for several minutes
before discarding.
To prepare the infused simple syrup, combine a quarter cup water, honey,
lemongrass, and cinnamon sticks in a small saucepan and place over
medium heat. Simmer, stirring occasionally, until mixture is heated
through and starts to thicken, approximately 4-5 minutes.
Remove from heat and pour through a fine mesh strainer to separate the
solids from the liquid. Discard solids and set the remaining simple
syrup aside to cool.
Combine the brewed tea, lemon juice, and remaining cup of water in a large
pitcher. Add infused simple syrup, to taste, and stir to combine.
To serve, fill four chilled glasses with ice before adding the sweetened
iced tea mixture. Garnish with lemon slices and sprigs of fresh mint,
if using, and serve immediately. Enjoy!
