In the bowl of a stand mixer, using the whisk attachment, whip mascarpone cheese and butter until smooth. Add heavy cream, the Redpath® Granulated Sugar, lemon juice, and salt. Start on slow speed until it just comes together, slowly increasing the speed to high until mixture becomes thick; about 5 minutes.
Transfer to a jar with a tight fitting lid or an airtight container and chill in the refrigerator until ready to use. Can be stored in the fridge for up to a week.
*Place bowl and whisk attachment into the freezer to chill. This ensures the heavy cream stays cold and whips up properly.
*For maximum volume and smoother texture, ensure heavy cream is cold (straight from the fridge, if possible) when whipped.
*Use as a spread on scones, toast, or to garnish fresh summer berries.
