Preheat oven to 170 ℃ (340 ℉).
Combine the milk and cream.
Split the vanilla bean lengthwise and using the end of a teaspoon or small knife, scrape the seeds into the cream and milk mixture (best result will be achieved if this step is done the day before but not a must).
Using a whisk, break up egg yolks in a large stainless steel bowl.
Whisk the sugar into the eggs until dissolved.
Using a rubber spatula or large spoon, stir in the cream and milk, try to avoid making bubbles but do ensure all the egg has dissolved into the cream mixture.
Pass the mixture through a fine sieve into a pouring jug.
Place the ramekins in a large oven dish or tray that can accommodate all the ramekins and some water. Fill the ramekins with the mixture to approx half a fingers thickness from the top.
Place the oven dish on the oven shelf and fill the dish with water until the ramekins are sitting in water 2/3rds of the way up their side (water bath).
Bake for approx 40 minutes (half way through the baking process, turn the tray around to ensure even heat distribution).
Remove the Brulees from the baking tray and refrigerate for at least 3-4 hours.
