Now pour the egg mixture back into the remaining beer | cream mixture, whisking to incorporate the ingredients together and prevent any lumps. Place the pot back over low heat, whisking constantly. Create a pattern to scrape the whole bottom and edges of the pan, preventing any of the egg mixture to cooking or sticking to the bottom of the pot. The mixture will start to thicken up and come to a boil. Continue to whisk and let the pastry cream boil for 30 – 60 seconds, then remove from the heat. Stir in the chopped chocolate and continue to whisk until it has melted into the pastry cream. Remove the vanilla bean pod, scraping out any remaining seeds.
