Ingredients:
- 2 cups heavy cream (36% milkfat)
- 1 cup whole milk
- 3/4 cup granulated sugar
- 5 large egg yolks
- 1/4 tsp sea salt
- 1 whole vanilla bean
Instructions:
- Infuse the dairy. In a heavy bottomed saucepan, combine the 2 cups heavy cream, 1 cup whole milk, half of the granulated sugar, and the scraped seeds and pod of the vanilla bean. Note: Heating the pod along with the seeds extracts every ounce of flavor from the husk.
- Simmer gently. Heat the mixture over medium heat until it reaches a gentle simmer, approximately 175°F (80°C). Wait for small bubbles to ring the edge of the pan.
- Steep the aromatics. Remove from heat, cover with a tight lid, and let steep for 20 minutes. Note: This resting period allows the vanilla bean oils to fully migrate into the fat of the cream.
- Prep the yolks. In a separate medium bowl, whisk the 5 egg yolks with the remaining sugar and sea salt. Continue until the mixture is pale and slightly thickened.
- Temper the eggs. Slowly drizzle one cup of the warm milk mixture into the yolks while whisking constantly. Note: This gradually raises the temperature of the eggs so they don't scramble.
- Thicken the custard. Pour the tempered egg mixture back into the saucepan and cook over medium low heat. Stir constantly until the custard reaches 170°F (77°C) and coats the back of a spoon.
- Refine the texture. Strain the custard through a fine mesh sieve into a clean bowl to remove the pod and any lumps. Stir in the pure vanilla extract immediately.
- Chill thoroughly. Cover the surface directly with plastic wrap to prevent a skin from forming and refrigerate for at least 6 hours. Note: Overnight is even better for flavor development.
- Churn and freeze. Churn the chilled base in your ice cream maker. Process until it looks like thick soft serve.
- Final cure. Transfer to an airtight container and freeze for 4 hours until firm. Expect a dense, scoopable consistency.
