* If vanilla bean is not available, use 1 teaspoon of vanilla paste or 1 teaspoon of vanilla extract. If using vanilla extract, do not steep the heavy cream. As the heavy cream is warming up, quickly whisk together the sugar, salt, and egg yolks in a separate bowl. Remove the heavy cream from the heat and stir in the vanilla extract. Continue following the instructions above with mixing the heavy cream and egg yolk mixture. If using vanilla paste, follow the same instructions for vanilla beans.
