Muddle a few slices of cucumber and some rosemary leaves in a cocktail shaker with 3/4 oz. lime juice and a pinch of sugar. Add 2 oz. tequila and ice. Shake. Strain into highball glass with ice. Pour over 1 oz. tonic water. Garnish with rosemary sprig.
Once the drink was made, I couldn't just leave it at that. I had some tomatillos that I got from my farm share today, so I chopped them into a simple salsa with onion, chili, sea salt and lime. Simple. And perfect for a little alone time.
