Preheat oven to 300 degrees.

Melt chocolate with 1/2 cup cream, over simmering water. Remove from heat.

Warm remaining milk and cream with sugar just until sugar is melted.

Whisk yolks and slowly stir into this milk mixture.

Set melted chocolate mixture in bowl.

Using a mesh sieve, pour yolks through into the melted chocolate mixture and combine. Optionally at this point, you could stir in a splash of liquor.

Pour into 4 ramekins or little espresso cups. Place in baking dish, and bring water up to 1/2 inch from top.

Bake for 45 minutes if using 4 ramekins, 40 minutes if using espresso cups.

Serve warm with whipped cream, or refrigerate and serve cold. You can make this the day before.
