2/3 cup (160 milliliters) sugar, plus 6 tablespoons (90 milliliters) for topping
1/8 teaspoon (0.5 milliliters) salt
Preheat the oven to 285 F (140 C). Add cream, milk and vanilla to a saucepan. Cook over low to scald milk. In a separate bowl, whisk together egg yolks, sugar, and salt. Gradually add milk mixture to egg mixture and whisk to incorporate. Strain. Pour into ramekins. Add to a baking tray filled with a few inches of water. Cover the tray with a sheet of foil. Bake for 40-45 minutes, or until slightly wiggly but not runny. Remove and let cool completely. Sprinkle the top with a thin layer of sugar. Use a kitchen torch to bubble and caramelize sugar – or place it in the oven under broil. Let cool completely.
