Make Strawberry Syrup: Wash and slice 2 cups of fresh strawberries. In a medium saucepan, combine strawberries with 1 cup granulated sugar and 1 cup water. Cook over medium heat for about 30 minutes, stirring occasionally until it reduces to a syrupy consistency. Strain the syrup through a fine mesh sieve into a bowl, discard solids, and allow to cool completely.

Brew the Tea: Bring 2 cups of filtered water to a rolling boil. Remove from heat and add 3-4 black tea bags. Let it steep for 5 minutes. Stir in 1/4 cup sugar until dissolved and let cool to room temperature.

Combine Ingredients: In a large pitcher, pour the cooled strawberry syrup, add brewed tea, and stir gently. Pour in 2 cups of cold water with the juice of one freshly squeezed lemon. Stir until combined.

Serve and Garnish: Fill glasses with ice cubes and gently pour the iced tea mixture over the ice. Garnish with mint leaves and slices of fresh strawberries.
