Brew the tea: Make a strong cup by steeping 1 black tea bag in 1/2 cup hot water for 5 minutes. Remove the bag and chill the tea in the fridge or with a couple of ice cubes.
Prep your glass: Fill a tall glass to the top with ice.
Cold ice is key to a crisp, restaurant-style drink.
Sweeten the base: In a small cup, combine the lemon juice and your sweetener. Stir until fully dissolved. If using honey, warm it slightly so it blends easily.
Build the drink: Pour the chilled tea over the ice.
Add the sweetened lemon juice. Give it a quick stir to mix.
Add bubbles: Top with sparkling water. Stir gently to keep the fizz.
Finish with flair: Add a pinch of salt if you like, then tuck in mint, berries, or a lemon slice.
Taste and adjust sweetness or tartness as needed.
Serve right away: This is best cold and fresh, with plenty of ice and bubbles.
