Prepare Your Glass: Start by filling a highball glass with ice. This will ensure your drink stays nice and chilled.

Mix the Ingredients: In a shaker, combine the tequila, crème de cassis, and fresh lime juice. Shake well to mix the flavors together.

Pour and Top Off: Strain the mixture into the prepared glass over the ice. Then, top off with ginger beer, gently stirring to combine.

Garnish: Add a lime wedge or slice for a touch of citrusy flair.
