Since I didn't post a new cocktail this weekend, here's a mid-week one for you. I found it in my Bartender's Black Book. It's called the Berta.
It's 2-oz. tequila, 2-oz. honey, and 1-oz. lime juice stirred until the honey dissolves. Add lots if ice, and fill the glass with soda water. It was surprisingly amazing. You couldn't taste the tequila at all. It was just sweet and light and very summery. Highly recommended!
