Hull 4-5 fresh strawberries and slice them into quarters. Place them in a cocktail shaker without ice.

Using a muddler or the back of a bar spoon, gently press the strawberries against the bottom of the shaker to release their juices and break them into smaller pieces. Press firmly but briefly to avoid crushing seeds.

Pour 1.5 ounces of chilled vodka and 0.5 ounces of strawberry liqueur (if using) into the shaker with the muddled berries.

Add 0.75 ounces of freshly squeezed lemon juice and 0.5 ounces of simple syrup directly into the shaker.

Add a handful of ice cubes to the shaker and seal the top firmly. Shake vigorously for 10-12 seconds until the outside of the shaker is frosty.

Chill a martini or coupe glass by filling it with ice and cold water while shaking. Just before straining, discard the ice water.

Strain the cocktail into the prepared glass using a cocktail strainer. For a smoother texture, use a fine mesh strainer to catch any small strawberry pulp.

Rub the rim of the glass with a fresh lemon wheel and dip it into granulated sugar for a sparkling effect.

Garnish the drink with a fresh strawberry slice and a thin lemon wheel. Serve immediately.
