Cold punch with prosecco, slightly reminiscent of the taste of a Kir Royale cocktail.
Pour liqueur, blackcurrant syrup, jam and lemon juice into a shaker. Mix. Filter the shake with a strainer into a chiller glass and pour in lump ice.
Add prosecco and stir. Get up tube. From above, make a hat from the crash. Decorate with prunes and whipped cream.
