Prepare the Ingredients - Wash the raspberries and mint leaves under cold running water. Slice the lime in half and use a citrus juicer or a hand-held reamer to extract the juice. Prepare the simple syrup by mixing equal parts of water and sugar in a bowl until fully dissolved.

Muddle the Mint Leaves - Add the mint leaves to a cocktail shaker and gently muddle them with a muddler, until they release their oils. Add the raspberries, lime juice, simple syrup, and vodka to the cocktail shaker, and fill with ice. Shake vigorously for 20 seconds to chill the drink and combine the ingredients.

Strain and Serve - Strain the cocktail into a Collins glass filled with crushed ice. Use a cocktail strainer to remove any bits of mint leaves and raspberries. Top up with more crushed ice if necessary. Garnish with fresh raspberries and a mint sprig. Serve the Garden of Delights cocktail immediately and enjoy!
