Preheat the oven to 300 degrees. Place the six ramekins in a large baking dish. Divide the blueberries between the ramekins.
In a mixing bowl, whisk together the yolks and maple syrup.
In a three quart saucepan, over medium heat, cook the cream just until it starts to steam. Slowly, while whisking the yolk mixture, pour the cream through a sieve into the yolks. Take care to pour the cream in very slowly so as not to scramble the eggs. Pour this all into a measuring cup or pitcher to make the next step easier.
Divide the cream and yolk mixture between the ramekins.
Place the pan in the oven, and then pour cold water into the pan, so that it comes three quarters of the way to the top of the ramekins. Bake for 25 to 30 minutes. They should just be slightly jiggly in the middle. Place them in the refrigerator for four hours.
Sprinkle a teaspoon and a half of sugar over each pudding. Using a kitchen torch, brown the tops of the puddings. Serve right away.
