Get everything ready. Tip: put the glass half an hour before serving in the freezer for an extra nice ‘icy’ appearance.
Pour the apple juice into a bowl and add the Lecithin. Mix with a hand blender to create a layer of foam. Make sure that a corner of the hand blender protrudes above the liquid to mix air. Tip: take a mixing bowl with high edges – it can splash.
The foam easily stays good for half an hour.
Mix the Cava, vodka and Lemon Sorbet with the hand blender in a mixing bowl with high edges (this can also splash …).
If necessary, insert a long spoon into each glass and scoop to approx 1cm nder the edge of the Sgroppino in the glasses. Gently spoon a spoonful of foam onto the scropino and form a nice high point of the foam or dress it further with a leaf of mint.
