Make the simple syrup first. Combine 1 cup water and 1 cup sugar in a small pot. Heat over medium heat and stir until sugar is dissolved. Remove from heat.
Juice the lemons and add the 1 cup juice to the tea. Start by adding 1/2 cup of the simple syrup to the lemonade mixture. Taste and add more syrup as desired. I added another 1/4 cup.
