Melt each chocolate (one at the time) over a double boiler. Then set aside and let cool to room temperature.
When all melted chocolate has chilled, start whipping the cream, whip to whip to soft-medium peaks.
Fold ⅓ of the whipped cream into each chocolate mixture. Whip until combined and no streaks remain.
