In a medium saucepan, bring 4 cups of water to a boil.

Once boiling, remove from heat and add the black tea bags. Let steep for 5-7 minutes, depending on your desired strength.

Remove the tea bags and stir in the sugar until fully dissolved.

Allow the tea to cool to room temperature, then stir in the passion fruit juice.

Refrigerate the tea for at least 1 hour to chill.

To serve, fill glasses with ice cubes and pour the chilled passion fruit tea over the ice.

Garnish with fresh mint leaves and lemon slices before serving.
