Preheat oven to 325F and set a large pot of water to boil
In a bowl, beat egg yolks with sugar until light
Heat cream, salt, and vanilla to 158F in saucepan
Pour 1/4 of cream mixture over egg yolks and stir
Pour cream-sugar-egg mixture into saucepan with the rest of the cream and stir
Pour mixture into two 6oz ramekins. Fill large baking dish with boiling water about halfway, then place ramekins in baking dish and bake until just set (barely wiggles). Temperature throughout the custard should be no lower than 176F. This will take about 50 minutes
Let cool to room temperature, then refrigerate for at least a few hours or overnight
Just before serving, sprinkle about a teaspoon of sugar evenly over the top of each custard. Use a torch to gently melt and brown the sugar. After torching, let it sit to cool for a couple minutes
