Preheat the oven to 180°C (350°F). Place cut strawberries into a baking dish and scatter with raw sugar. Roast for 20 minutes, until strawberries are softened and have released some juice. Set aside to cool.

Dip the rims of your glasses in lime juice or water and press into the pink salt evenly to coat the rim. This is optional, but it definitely does add something to the drink.

To make the cocktail, place about half of the strawberries and some of the syrup in the bottom of each glass and muddle.

Add the grapefruit and lime juices, and the tequila evenly between each glass and stir to combine. Add some ice and top up with ginger beer. Add extra sliced strawberries, for garnish if desired.
