• Cut off the top and bottom of the grapefruit and then follow along the curve of the grapefruit with a paring knife to remove the skin and membrane. Then cut in between the white membranes to remove a now clean segment of fruit. Do this for the entire grapefruit. Use the remaining pulp to squeeze out the juice. Measure out 1 ounce.
• With your lime, make two twists from the peel for garnish (watch our video to see how I do this), and then squeeze for the juice. Measure out 1 ounce. If you don’t have a tool to make lime twists, you can just cut slices from a second lime instead.
• Mix together all chilled ingredients into a measuring cup, pitcher, or shaker. Add a few pieces of grapefruit segments into two glasses. Pour chilled drink on top of the segments, divided among the two glasses. Garnish glasses with lime twists
  

TIPS: Most likely you will only need 1 grapefruit and either 1 or 2 limes to get the proper amount of juice and garnish.
