Aquafaba, the viscous fluid from canned chickpeas, is the surprising key to making a plant-based whipped topping. The process is pretty miraculous: The liquid whips up to a thick, fluffy foam that mimics whipped cream. Just be sure to use the liquid from unsalted chickpeas for the best results (we like Eden brand).
How to Make It
Preheat oven to 375°F. Line a rimmed baking sheet with parchment paper. Place strawberry halves, salt, and 2 tablespoons sugar in a medium bowl; toss to coat. Spread strawberries in a single layer on prepared baking sheet. Bake at 375°F for 25 minutes. Let strawberries cool slightly, about 20 minutes.
Drain liquid from can of chickpeas into bowl of a heavy-duty stand mixer fitted with whisk attachment (reserve chickpeas for another use). Add vanilla and cream of tartar to chickpea liquid, and beat on medium-high speed, gradually adding remaining 2 tablespoons sugar, until soft peaks form, 6 to 8 minutes.
Transfer roasted strawberries and juice from pan to a high-powered blender. Add ice, tequila, lime juice, mint leaves, and agave nectar. Process on high speed until creamy, about 1 minute. Pour evenly into each of 8 glasses; top each with about 1/3 cup aquafaba whip.
If desired, thread blueberries onto each of 8 small skewers, and add to each glass with a mint sprig.
