Step 1: Prepare Your Glass

Begin by preparing your martini glass. Pour a bit of sugar onto a small plate. Take a lemon wedge and run it around the rim of the glass. Then dip the rim into the sugar, coating it evenly. Set the glass aside to dry slightly—this adds both beauty and a touch of sweetness to each sip.

Step 2: Gather and Chill Your Ingredients

Ensure all your ingredients are cold, especially the vodka and club soda. A well-chilled cocktail brings out the crisp, refreshing nature of this drink.

Step 3: Juice the Lemon

Fresh lemon juice is crucial. Roll the lemon on a countertop before slicing to release more juice. Using a handheld citrus juicer or reamer, squeeze out enough to measure ¾ oz. Strain it to remove any seeds or pulp.

Step 4: Make the Simple Syrup (if needed)

If you don’t have store-bought simple syrup, you can quickly make your own. Combine equal parts sugar and water (e.g., ½ cup each) in a saucepan, heat gently while stirring until the sugar dissolves completely, then let it cool. Store any leftover syrup in the refrigerator for up to two weeks.

Step 5: Combine in a Shaker

In a cocktail shaker filled with ice, pour:

• 2 oz vodka

• ¾ oz fresh lemon juice

• ½ oz elderflower liqueur

• ½ oz simple syrup

Seal the shaker and shake vigorously for 15–20 seconds. This chills the ingredients thoroughly and slightly dilutes them for a smoother taste.

Step 6: Strain and Pour

Using a fine mesh strainer or the shaker’s built-in strainer, pour the mixture into your prepared, sugar-rimmed martini glass.

Step 7: Add the Fizz

Top off the cocktail with a gentle splash of club soda. Pour slowly to avoid overflowing or flattening the bubbles. You only need about ½ to 1 oz—just enough to add some sparkle.

Step 8: Garnish

Garnish with a thin lemon wheel floated on top or, if available, a small edible elderflower blossom for an elegant flourish.

Step 9: Serve Immediately

This cocktail is best enjoyed fresh while it’s still cold and sparkling. Serve immediately and savor the fragrant, citrusy, floral beauty in every sip.
