Cooking the Custard
- Return the tempered egg mixture to the saucepan and cook over medium heat, stirring constantly until thickened (about 5-7 minutes).
- Remove from heat and stir in vanilla extract.
Chilling
- Cover the custard with plastic wrap touching the surface to prevent a skin from forming and chill in the fridge for at least 1 hour.
Whipping Cream
- In a separate mixing bowl, whip heavy cream until soft peaks form (about 3-5 minutes).
- Be cautious not to overwhip.
Combining the Mixtures
- Once chilled, gently fold the whipped cream into the custard using a spatula to maintain the airy texture.
