For the simple syrup: In a saucepan, bring water to a boil. Reduce to medium-high heat and add sweetener. Stir to dissolve and continue to heat for 10 minutes. Pour into heat-safe glass container and refrigerate to chill. Store unused portion in airtight container in refrigerator for up to four weeks.
For the zero-proof cocktail: Combine gin, lemon juice and Eat Fit Simple Syrup in a small shaker tin filled with ice. Shake and double strain into a tall champagne flute. Top with zero-proof sparkling wine and garnish with expressed lemon swath.
Note: The lemon juice really fizzes up the sparkling wine. Tilt the champagne flute as you pour the sparkling wine to keep it from overflowing.
