Muddle strawberries, mint leaves, and sugar in a cocktail shaker. Pour hot water over it and cover for five minutes.
While strawberries steep, whip heavy cream with sugar and a splash of Chambord (or vanilla, if you prefer). Whip until stiff peaks form. Set aside.
When strawberries are done steeping, pour in simple syrup, Gran Marnier, Chambord, Vodka, and add ice. Re-cover and shake for 30 seconds.
Strain into a milkshake glass (it may be easier to strain with a small cocktail strainer as the strawberries might clog the cocktail strainer holes) until all of the juice is in the glass.
Pour soda water* over the juice. The soda should be about an inch and a half below the milkshake glass top. Spoon the whipped cream over it. Insert a straw and garnish with a mint leaf and a scone-strawberry skewer.
Notes
This is already quite a strong drink, but if you were looking to fortify it, you could use rose champagne instead of soda water. I have not tried it before, but I imagine it could be nice.
