Method
Make the custard
- Heat the heavy cream and whole milk in a saucepan over medium-low heat until steaming, not boiling, with small bubbles forming around the edges.
- In a bowl, whisk the egg yolks with the granulated sugar until smooth and slightly lighter in color.
- Slowly whisk the steaming cream mixture into the egg yolks in a thin stream to temper, keeping the egg mixture moving.
- Return everything to the saucepan and cook over medium-low heat, stirring constantly, until the custard reaches 175F and thickens enough to coat the back of a spoon.
Chill the base
- Strain the custard through a fine mesh sieve into a clean container to remove any bits of cooked egg.
- Stir in the vanilla extract and salt, then cool completely at room temperature before refrigerating.
- Refrigerate at least 4 hours (until very cold and set enough to churn).
Churn and freeze
- Churn the cold custard in an ice cream maker according to the manufacturer’s instructions, until it reaches a soft-serve consistency.
- During the last 2 minutes of churning, add the crushed chocolate sandwich cookies, letting some stay chunky while others dissolve slightly for a cookies-and-cream swirl effect.
- Transfer the churned ice cream to a container and freeze until firm.
Notes
Pro tip: temper slowly and cook only until 175F—overheating can create a grainy custard. Store covered in the freezer for up to 2 months; thaw in the fridge 10–15 minutes before scooping. Freezer: yes. Dietary swap: use lactose-free whole milk and lactose-free heavy cream to keep the same texture while reducing lactose.
