To make the frosé...
Freeze 500ml of M&S La Dame en Rose for 4-6 hours.
In a separate container add 1 shot of vodka, juice of 1 lemon, 1 tsp sugar and mix.
Spoon the frozen La Dame en Rose into a blender along with a handful of your chosen berries.
Blend the frozen rosé and berries along with the lemon, sugar and vodka until smooth.
Decant into a glass with a sugar rim and garnish with a slice of lemon.
