For the pastry cream

In a large bowl, mix the egg yolks, sugar, cornstarch and salt and whip together until thick. In a medium saucepan over medium heat, bring the milk to a boil, then remove from heat.
In a slow and steady stream add about 2 tablespoons of milk to the egg mixture, then, while whisking steadily, add the rest of the milk. Pour mixture back into the saucepan, return to medium heat, continue to whisk steadily. Bring to a boil then whisk until the mixture thickens. Remove from heat and whisk in chocolate. Rest mixture off heat for 5 minutes.
Whisk in the butter, one piece at a time, until pastry cream is smooth and silky. Transfer to a clean bowl and cover the surface with plastic to prevent a “skin” from forming. Chill until cold.
