Mix the jam well with the whipped cream, a cream cup full of milk (6 portions at a time) and the juice of one lemon. Fill into an ice cube mold and freeze.
For each drink, mix about 3 ice cubes with one cup of milk in a hand mixer. Fill into glasses. Put 1 orange wedge and 1 cherry on each skewer and place in glasses.
Dust the drink with nutmeg.
