Preheat the oven to 150°C and place 7 standard-sized ramekins into a large roasting dish.
Add the yolks, sugar, and salt to a bowl of an electric mixer fitted with a whisk attachment. Whisk until just combined but not aerated.
In a medium saucepan set over medium-high heat, add the cream. Allow the cream to come to a simmer, do not boil. Remove from the heat.
Add the chopped chocolate to the cream and stir with a wooden spoon until melted.
With the motor of the electric mixer running at a low speed, slowly add the hot cream mixture to the egg mixture.
Once the cream mixture has been added to the egg and sugar mixture, pour the mixture through a sieve and into a jug. Fill the ramekins with the custard mixture.
Place the oven tray into the oven. Once in the oven, fill the oven tray halfway up the sides of the ramekins with hot water. Bake in a preheated oven for about 25 minutes or until just set.
Remove the roasting dish from the oven and remove the ramekins from the water bath. Place the ramekins in the fridge to set for a few hours, ideally overnight.
When you are ready to serve, sprinkle a layer of granulated sugar over the surface of each crème brulee, and use a handheld blow torch to melt the sugar. Serve and enjoy!
