Robin found out how to mix a cocktail named “Nightfall” :

ingredients
4 cl white rum
4 cl vodka
1 cl lemon juice
12 cl apple juice
4 cl cola
Results in approx. 16 cl without ice.

Preparation
Put rum and vodka together with limes and apple juice with ice in a shaker. Shake well.
Pour into a long drink glass and top up with cola.

This night was made for falling!
