Have glassware chilling in freezer 15-30 minutes prior to making cocktail
In small tin add gin, simple syrup, and fresh squeezed lemon juice
In large tin add 1/2 a bar scoop of crushed ice or ice from pebble mold
Combine tins, form a seal, and whip shake until the ice in the tins dissolves
Break seal and dirty pour cocktail into chilled glass
Pack glass with crushed ice, or pebble mold ice to the brim
Drizzle ½ oz of crème de mûre over top of cocktail and let it sink to the bottom
Garnish with cocktail pick holding three fresh blackberries
Enjoy!!!
