01 - Bring 2 cups of water to a boil in a small pot or kettle over high heat.
02 - Add black tea bags to the boiling water. Remove from heat and let steep for 4–5 minutes to achieve a strong brew. Remove and discard tea bags.
03 - While the tea is still hot, stir in the sugar until completely dissolved.
04 - Allow the sweetened tea to cool to room temperature, approximately 15–20 minutes.
05 - Stir in the fresh lime juice once the tea has cooled.
06 - Fill two tall glasses with ice cubes. Pour the lime tea over the ice, dividing evenly between glasses.
07 - Garnish each glass with a fresh lime slice. For a creamy variation, drizzle ½ tablespoon sweetened condensed milk over each glass and stir gently before serving.
