In a saucepan, combine the heavy cream, seeds from the split vanilla bean, and the vanilla bean pod. Heat over medium until it just starts to steam, then remove from heat and let it sit for 15 minutes to infuse the vanilla flavor.
In a mixing bowl, whisk together the egg yolks, 1/2 cup of granulated sugar, and a pinch of salt until the mixture is pale and slightly thickened.
Remove the vanilla bean pod from the cream mixture. Slowly pour the warm cream into the egg mixture while whisking continuously to temper the eggs. Make sure to incorporate all the cream for a smooth consistency.
Stir in the vanilla extract after mixing thoroughly.
Strain the mixture through a fine mesh sieve into a large measuring jug to remove any lumps.
Pour the custard into six ramekins, leaving a little room at the top.
Place the ramekins in a baking dish. Fill the baking dish with hot water until it reaches halfway up the sides of the ramekins (a water bath helps the custards bake evenly).
Bake for 30-35 minutes or until the edges are set but the centers still have a slight jiggle.
Remove from the oven and water bath, then let cool at room temperature for about an hour. Refrigerate for at least 2 hours or overnight for best results.
When ready to serve, sprinkle a thin layer of sugar on top of each custard. Using a kitchen torch, carefully melt the sugar until it forms a crispy, golden caramel layer. If you don’t have a torch, you can place the ramekins under the broiler for a minute or two, just watch closely to prevent burning.
Allow the caramel crust to harden for a minute before serving for the best texture contrast.
