Classic black tea becomes way more interesting when you add hibiscus, orange zest, and seltzer. Bright, bubbly, and refreshing, it makes an excellent summer thirst-quencher.
Bring sugar and 1 cup water to a boil in a saucepan; stir until dissolved. Remove from heat; add hibiscus, tea bags, and orange zest. Steep 4 minutes.
Strain through a fine-mesh sieve; press gently to release liquid from bags. Discard solids; let cool completely.
Add 3 tablespoons tea mixture to a glass filled with ice. Top with seltzer. Serve, with orange slices.
If you'd rather use loose-leaf tea, just remember this handy conversion: One teaspoon equals one bag.
