In a medium saucepan, combine the heavy cream, the scraped seeds from the vanilla bean, and the split vanilla bean pod. Heat over medium until it begins to simmer, then remove from heat. Let it sit for about 15 minutes to infuse.
In a mixing bowl, whisk the egg yolks, granulated sugar, vanilla extract, and salt together until the mixture is pale and slightly thick.
Remove the vanilla bean pod from the cream mixture. Slowly pour the warm cream into the egg yolk mixture while whisking continuously to prevent the eggs from scrambling.
Strain the mixture through a fine-mesh sieve into a clean bowl to get rid of any curdled egg bits.
Place four ramekins in a baking dish. Pour the custard evenly into each ramekin.
Carefully fill the baking dish with hot water until it reaches halfway up the sides of the ramekins.
Bake in the preheated oven for about 30-35 minutes, or until the custard is set but still slightly jiggly in the center.
Remove the ramekins from the water bath and let them cool to room temperature, then refrigerate for at least 2 hours (or up to overnight).
When ready to serve, sprinkle a thin layer of granulated sugar on top of each crème brûlée. Using a kitchen torch, caramelize the sugar until it forms a crisp, golden crust. If you don’t have a torch, you can place the ramekins under the broiler for 2-3 minutes, watching carefully to prevent burning.
Allow the caramelized sugar to harden for a couple of minutes before serving.
Notes
For best results, refrigerate the custards overnight before caramelizing the sugar.
