Top one or two shots of tequila with grapefruit soda. The classic brand to use is grapefruit-flavored (“Toronja”) Jarritos, but you could try it with any brand you like, or DIY with grapefruit juice, seltzer, and simple syrup. Garnish with a lime wedge.
Muddle a cucumber slice, lemon slice, and a sprig of fresh mint in the bottom of your glass. Add a shot or two of Pimm’s and top with ginger ale. Okay, so including the veggies this may be a few more than two ingredients. But it’s still dead easy to make and a perfect summer drink in every way
