In this tropical take on the Arnold Palmer, lime wedges, thyme sprigs, and fresh ginger are muddled together, then mixed with chilled rooibos tea.
Combine sugar, ginger, 8 thyme sprigs, and quartered lime in a cocktail shaker. Muddle until lime quarters release their juices and ginger and thyme begin to break down. Add lime juice, stirring until sugar has completely dissolved. Strain mixture into a pitcher partially filled with ice, or divide evenly among 4 ice-filled glasses. Top with tea, stirring to evenly combine. Garnish with thyme sprigs, ginger slices, and lime wheels; serve.
