Prep Glass: Fill a Collins glass with ice cubes. Give it a stir to chill it and set it aside.
Prep Cherries: Remove the pits from 5 fresh cherries.
Muddle Cherries: In your shaker, add the cherries and 1 oz fresh lemon juice. Muddle well to extract the flavor from the cherries.
Add Simple Syrup: Add ¾ oz simple syrup.
Add Gin: Measure and pour 2 oz Gin into the shaker as well.
Shake: Fill the shaker with ice, close it, and give it a good shake (10-15 seconds).
Strain: Remove the ice in the Collins glass and refill it with fresh, new ice cubes. Then, using both the cocktail strainer and the fine strainer, strain the shaken drink into the ice filled glass.
Top with Soda: Top off with approx. 3-4 oz soda water (adjusting to taste and to the size of the glass).
Stir: Using a bar spoon or long stirrer, stir gently to combine.
Garnish: Garnish with a lemon slice and a cherry (fresh or candied) and serve immediately.
