Carefully wash fresh currants and drain well. Squeeze the lemon.
Mix the mascarpone with yogurt, lemon juice, amaretto, sugar and vanilla sugar until smooth. Strip the berries from the panicles with a fork and fold into the mascarpone cream. Roughly chop the cantuccini, meringue and chocolate and carefully fold everything into the cream.
Divide between 4 glasses and decorate with currant panicles if necessary.
