Preheat your oven to 160°C. Place 5 ramekins of 180ml (6oz) size in a deep baking dish.
In a saucepan, combine the heavy cream, vanilla extract (or split vanilla bean with seeds), and a pinch of salt.
2 cups (500ml) heavy cream, 2 tsp vanilla extract or 1 vanilla bean, A Pinch of salt
Tip: If using vanilla extract add it after removing from the heat.
Heat over medium heat until hot and steaming, but do not boil. Remove from heat and let sit for 5 minutes. If using a vanilla bean, remove it.
Tip: The cream should be heated to about 75–82°C— hot and steaming, but not boiling. If you don’t have a thermometer, heat it just until small bubbles form around the edges and steam rises.
In a bowl, whisk the egg yolks and granulated sugar until pale, thick, and slightly creamy.
5 large egg yolks, ½ cup (100g) granulated sugar
Slowly pour the warm cream into the egg mixture while whisking constantly. This prevents the eggs from curdling.
Strain the mixture through a fine-mesh sieve to remove bubbles and ensure a smooth texture.
Divide the custard evenly among the ramekins. Place the baking dish in the oven and carefully pour hot water into the dish until it reaches halfway up the sides of the ramekins.
Bake for 30–35 minutes, until the edges are set but the centers still jiggle slightly when shaken.
Remove ramekins from the water bath and let cool to room temperature. Refrigerate for at least 2 hours, preferably overnight.
Just before serving, sprinkle an even layer of sugar (about 1–2 teaspoons per ramekin) over the top.
Extra sugar
Use a kitchen torch to caramelize until golden and crisp.
(Alternatively, broil for 1–2 minutes, watching very closely.)
Let the caramelized sugar harden for 1–2 minutes, then serve immediately.
