Ramble

In a shaker, combine the gin, lemon juice, and ¾ ounce of the simple syrup.

Short shake with 3, ice cubes, then strain into a highball glass filled with crushed ice.

Empty the shaker, then add the raspberries and the remaining ½ ounce simple syrup.

Gently muddle the raspberries, then pour over the top of the drink and serve with a straw.
