Infuse the Milk: In a medium saucepan, combine milk and vanilla bean seeds and pod. Heat over medium heat until just simmering. Remove from heat and let it steep for 10 minutes. If using vanilla extract, add it after heating the milk.
1 cup whole milk, 1 vanilla bean, split and seeds scraped
Prepare the Gelatin: In a small bowl, sprinkle gelatin over cold water. Let it stand for 5 minutes to bloom.
1 envelope unflavored gelatin, 2 tbsp cold water
Whisk the Egg Yolks: In a mixing bowl, whisk together egg yolks and sugar until pale and thick.
4 egg yolks, 1/2 cup granulated sugar
Temper the Eggs: Gradually pour the warm milk into the egg mixture, whisking constantly. Return the mixture to the saucepan.
Cook the Custard: Cook over low heat, stirring constantly, until the mixture thickens enough to coat the back of a spoon (about 5-7 minutes). Do not let it boil.
Add Gelatin: Remove from heat and strain the custard through a fine mesh sieve into a clean bowl. Stir in the bloomed gelatin until fully dissolved.
Cool the Mixture: Place the bowl over an ice bath or chill in the refrigerator, stirring occasionally, until the mixture is cool but not set.
Whip the Cream: In a separate bowl, whip the heavy cream to soft peaks.
1 cup heavy whipping cream
Fold Together: Gently fold the whipped cream into the cooled custard until fully combined.
Set the Crème: Pour the mixture into ramekins or molds. Cover and refrigerate for at least 4 hours, preferably overnight.
Serve: To unmold, dip the ramekins briefly in warm water and invert onto serving plates. Garnish with fresh berries and mint leaves if desired.
