I've found this summer's "house cocktail"
A bit easier to make than Gina Chersevani's Gnome's Water which I mentioned a month or so ago, the Gordon's Cup also has the refreshing notes of lime and cucumber. It's on page 46 of the April issue of Bon Appetit, and it's served at LA's Comme Ca:
2/3 of 1 small lime, cut into 6 wedges
2 1/2 inch thick rounds of peeled cucumber
1/4 cup gin (I used the cucumber- and rose-scented Hendrick's)
1 1/2 tablespoons simple syrup
1 cup cracked ice
Pinch of sea salt
Place lime and cucumber in cocktail shaker; mash with muddler or wooden spoon until lime is juiced and cucumber is pulpy. Add gin and simple syrup, then ice. Cover; shake vigorously 3 times. Pour contents of shaker into rocks glass. Sprinkle with salt.
***Once my lavender is in bloom, I'll make a lavender-infused syrup, like Gina does for her Gnome's Water. And I think this drink would also be great topped with club soda.
