In a shaker, combine 2 oz of Empress 1908 Elderflower Rose gin, ½ oz of fresh lemon juice, ½ oz of simple syrup, and 1-2 bar spoons of red berry jam.
Fill the shaker with ice and shake the ingredients vigorously to chill and mix thoroughly.
Double strain the mixture into a glass using both a regular strainer and a fine mesh strainer to eliminate any pulp or seeds.
Garnish with a fresh berry or a twist of lemon peel for an extra touch of elegance.
