How to Make It
Toss the strawberries, blueberries, raspberries, granulated sugar, lemon zest and juice, and a pinch of salt in a large bowl. Let sit, stirring occasionally, until the berries are juicy, 20 to 30 minutes.
In a separate bowl, whip the cream, confectioners’ sugar, and vanilla until soft peaks form.
Layer the cream and berries in eight 8-ounce jars or parfait cups, dividing evenly.
