Special equipment: six 6-ounce ramekins and a kitchen blowtorch, optional
Combine the milk and cream in a large bowl. Sprinkle in the pudding mix and whisk until blended and slightly thickened, about 1 minute. Pour into six 6-ounce ramekins and refrigerate until set, about 1 hour.
Sprinkle the surface of each individual pudding with 1 teaspoon turbinado sugar. Gently shake each ramekin to evenly distribute the sugar over the surface of the pudding. Using a kitchen blowtorch, melt and caramelize the sugar so a thin shell forms over the surface. It's best to hold the torch a few inches away from the surface so the tip of the flame just touches the sugar. Let sit a few minutes before serving
If you don't have a blowtorch, you can use a broiler. Preheat the broiler to high. Put the ramekins with the sugared puddings on a baking sheet about 6 inches under the broiler and broil--with the oven door slightly open so you can watch--until the sugar is melted and caramelized. This should take only 1 to 2 minutes, so don't walk away. Let sit a few minutes before serving.
You can also caramelize the tops by heating the bottom of a metal flat-bottomed 1/2-cup measuring cup on the stove so it gets very hot. Carefully and gently press the bottom of the cup onto the sugared surface of each pudding for a few seconds to melt the sugar. Repeat, reheating the measuring cup once or twice in between if necessary.
Propane gas torches are highly flammable and should be kept away from heat, open flame and prolonged exposure to sunlight. They should be used only in well-ventilated areas. Follow torch manufacturer's instructions for use.
