Rinse 6 cups each with a capacity of approx. 150 ml with cold water and line them with cling film.
Soak the gelatine in cold water. Mix the jam, sour cream and lemon juice. Heat the liqueur, dissolve the pressed gelatine in it and mix quickly with the cranberry mixture. Beat the top and fold in. Place 1 amaretti in each cup, spread a little cream on top. Line the cups with the remaining amaretti - 4 per cup - and pour in the cream. Chill for 5 hours.
Then fall out of the cups, peel off the foil and garnish with cranberry jam.
