Courtesy of Smitten Kitchen‘s blog they give a photo detail of how to make a Porch Swing. Check out their site as well as the recipe below:
What you’ll need:
1 1/2 ounces (3 tablespoons) gin (Hendricks is specified; Tanqueray was used)
1 1/2 ounces (3 tablespoons) Pimm’s No. 1 liqueur (what’s Pimm’s?)
4 ounces (1/2 cup) homemade lemonade (recipe below)
7-Up or another lemon/lime soda
10 paper-thin half moon slices of cucumber (I used an “English”, unwaxed, cucumber)
Pour gin, Pimm’s and lemonade into tall Collins glass, then add a few ice cubes and a splash of 7-Up. Finish with cucumber slices.
1 part freshly squeezed lemon juice
1 part simple syrup, or to taste (I will use perhaps 1/2 or 3/4 of a part next time, see Note above)
2 parts water
Make simple syrup: [Please don’t buy it. I see it in stores and it vexes me.] Simmer one part water with one part sugar (I did a cup of each and ended up with about 1 1/2 cups simple syrup) until sugar has dissolved. Let cool. Or, you can use my speedier method where you simmer one part sugar with half as much water and once it has dissolved, add the second half of the water, cold, which cools the mixture down faster (when you like nothing to slow your pace to the nearest drink).
