1. In a deep mixing bowl, beat 1 cup heavy cream until soft peaks form.
2. Sprinkle 1 to 2 tablespoons granulated sugar over cream; beat until soft peaks return. Do not overbeat.
Note: If you prefer, you can replace the granulated sugar with an equal amount of confectioners' sugar; to prevent any lumps from forming, use a fine-mesh sieve to sift the sugar over the cream.
