   Tap the pan a few times to release any trapped air bubbles.

8. 8

   Pour the cold heavy cream into a large bowl. Set aside.

9. 9

   Separate 6 egg yolks from the egg whites and place the egg yolks into a heat-safe bowl. (Refrigerate or freeze the egg whites for later use).

    In a bowl, whisk together the egg yolks with sugar, vanilla extract, vanilla bean paste (if using), pinch of salt and set aside.
