The perfect low-key, low-alcohol drink to serve your employer in the afternoon if you know he'll need to be alert later. That said, you can always ramp up the booze factor with a nice British gin, if you feel so inclined.
2 cups Pimm's No. 1
3 cups brewed black tea, chilled
2 12-oz. bottles ginger beer, like Reed's or Gosling's
6 sprigs fresh mint, plus more for glass garnishes
Wash lemon and orange and slice them into thin rounds. Add citrus, Pimm's and tea to a large pitcher, stir, and keep in the fridge at least one hour or until chilled. To serve, stir in ginger beer, pour into glasses filled with ice, and garnish with mint and a lemon slice.
Optional: If you'd like a boozier drink, add 1 oz. of gin to your glass before serving, and then stir in the Pimm's mixture.
