In a small saucepan, combine 2 cups of sliced fresh strawberries, ¾ cup granulated sugar, and 2 cups of filtered water. Cook over medium heat for about 30 minutes, stirring occasionally, until the strawberries are soft and the mixture is fragrant. Strain the syrup into a container, discarding the solids, and allow it to cool to room temperature while you prepare the tea.

Bring 2 cups of water to a rolling boil in a separate saucepan. Remove the pan from the heat and add 5 black tea bags, allowing them to steep for 5 minutes. Discard the tea bags once steeping is complete.

Add ½ cup of granulated sugar to the hot brewed tea and stir vigorously until fully dissolved. Let the tea cool for a few minutes before mixing it with the strawberry syrup.

In a large pitcher, mix the cooled strawberry syrup with the brewed tea. Stir in ½ cup of freshly squeezed lemon juice, then add an additional 4 cups of filtered water.

Fill tall glasses with plenty of ice cubes, pour the Strawberry Iced Tea over the ice, and garnish with fresh mint and extra strawberry slices.
