Step 1

Use a pairing knife to cut the vanilla bean in half lengthwise, then use the knife to scrape out the seeds. Put the seeds, vanilla bean, sugar and water in a small saucepan over medium heat. Cook, stirring occasionally, until the sugar is fully dissolved. Transfer syrup and vanilla bean to a glass container and let cool. Store in the refrigerator for up to 1 month.

Step 2

Fill a cocktail shaker with ice and pour in the vodka, lemon juice and vanilla bean simple syrup. Shake until chilled, about 30 seconds. Strain into a chilled coupe or cocktail glass and enjoy.
