I get demands for this one, once people have tasted it once. This is fine enough for your finest occasion or company dinner when you want to impress, and easy enough for family dessert. The secret is not just in the ingredients, it is how it is cooked. Pay close attention and this will be a silky delight for all.
In small saucepan, combine half and half and vanilla. Heat until just scalded. DO NOT allow to come close to boiling. Allow to cool completely.
In a medium bowl, combine egg yolks, whole egg, and cane sugar. Beat until well mixed. Gradually stir in the cooled scalded half and half.
Add heavy cream and vanilla. Divide among ramekins or other small oven safe dessert baking cups.
Place in large baking pan or roaster and carefully, so as not to splash into the cups, fill pan with enough water to reach half way up the cups. Cover pan with foil or lid and bake.
Here is the Key Step: Bake only until custard is barely set. It should still quiver in the middle like it is partially liquid. dividing mix into 6 servings, I check it at 35 minutes and at 10 minute intervals after that. Don't let it get away from you as when it is baked to perfection, it will be silk on your tongue as well as delicious to the taste. Refrigerate until cool.
Preheat broiler or use kitchen torch. Sprinkle superfine sugar over tops of creme brule and place under broiler until caramelized but not burned. Refrigerate until cold and enjoy.
