The Evergreen Sparkler is a holiday cocktail that was created by food writer and author Jessica Strand and was first published in her book Very Merry Cocktails: 50+ Festive Drinks for the Holiday Season. It's a simple winter-inspired variation of the Tom Collins templates that pairs the classic's combination of gin, lemon, and carbonated water with an herbal syrup. For this version, however, the evergreen flavors are taken in a different direction by using pine syrup and tree-flavored bitters in addition to rosemary.
Add gin, pine syrup, lemon juice, and bitters to a shaker.
Fill shaker with cubed ice.
Shake for 10-20 seconds.
Fill a highball glass with fresh cracked ice.
Using a Hawthorne strainer, strain into highball glass.
Top with club soda.
Garnish with rosemary sprig.
