Ingredients
Nonstick cooking spray
1 tablespoon granulated gelatin
3 cups heavy cream
1 cup buttermilk
1/2 cup granulated sugar
1 vanilla bean, split
Pinch of salt
6 passion fruits
Confectioners’ sugar, as needed
6 Heart-Shaped Sugar Cookies
Edible flowers or raspberries, for garnish (optional)
Mint leaves, for garnish (optional)
Preparation
Lightly spray six 8-ounce molds with cooking spray; set aside. Place 3 tablespoons cold water in a small bowl; sprinkle gelatin over bowl and set aside to soften.
Place heavy cream and buttermilk in a medium saucepan and bring to a boil over medium-high heat. Add softened gelatin mixture and granulated sugar. Scrape vanilla bean seeds into cream mixture and add vanilla bean and salt; cook, whisking, until gelatin and sugar have dissolved. Strain mixture into a heatproof container with a pourable spout.
Divide cream mixture evenly between prepared molds. Transfer molds to refrigerator; chill until set, 6 to 8 hours and up to overnight.
Just before serving, scoop out flesh and seeds from passion fruits into a small bowl. Add enough confectioners’ sugar to sweeten as desired; stir until well combined.
To serve, place a cookie in the center of each of 6 plates. Invert a panna cotta onto each cookie and serve with passion fruit sauce. Garnish as desired; serve immediately.
