In a small saucepan over medium heat, melt 1 cup of sugar until it turns into a golden caramel. Pour the caramel into a 9-inch round baking dish, tilting to cover the bottom evenly.
In a mixing bowl, whisk together the eggs and 0.5 cup sugar until pale. Add the milk, cream, vanilla extract, and salt. Stir until combined.
Pour the custard mixture over the caramel layer in the baking dish.
Place the baking dish in a larger roasting pan. Fill the pan with hot water to halfway up the sides of the baking dish.
Bake in the preheated oven for 45 minutes or until the custard is just set.
Remove the dish from the water bath and let it cool completely. Refrigerate for at least 4 hours before serving.
To serve, run a knife around the edges of the dish and invert onto a serving plate.
Notes
For an extra touch, garnish with fresh berries or mint leaves before serving.
