Crimson Blush

Use 2:1 rich simple syrup for its listed portion.

Chill a martini glass by placing it in the freezer or filling it with ice water for a few moments.

Prepare some seasonal berries to use as a garnish.

Combine Ketel One Citroen Vodka, black raspberry liqueur, freshly squeezed pink grapefruit juice, and rich sugar syrup in a shaker filled with ice.

Shake the mixture vigorously until well chilled.

Fine strain the cocktail into the pre-chilled martini glass to remove any ice shards or pulp.

Garnish with the prepared seasonal berries before serving.
