|heavy cream, cold|
Into the bowl of a stand mixer, pour the cream and refrigerate for at least 15 minutes. (Chill the whisk beater alongside of the bowl.)
Starting on low speed and gradually raising the speed to medium-high as it thickens, whip the cream just until beater marks begin to show distinctly. Add the jam and beat just until stiff peaks form when the beater is raised. Use at once.
