Method
Make the lemon custard
- In a saucepan, heat the heavy cream and whole milk over medium heat until steaming, stirring occasionally for even warming.
- In a bowl, whisk the egg yolks with the granulated sugar until smooth, then slowly whisk the hot cream mixture into the yolks to temper.
- Return the mixture to the saucepan and cook over medium-low heat, stirring constantly, until the custard reaches 175°F and coats the back of a spoon.
- Strain the custard through a fine mesh sieve, then stir in the fresh lemon juice, lemon zest, vanilla extract, and salt until fully combined.
Chill and churn
- Set the custard in a heatproof bowl over an ice bath and cool completely, stirring occasionally until the surface is no longer warm.
- Refrigerate the custard at least 4 hours, until thoroughly chilled and ready to churn.
- Churn the chilled custard in an ice cream maker until it thickens to a soft-serve consistency, then transfer to a container.
- Freeze until firm, with a fully set texture for easy scooping.
Notes
Pro tip: temper the egg yolks slowly with a steady stream to prevent scrambling, and cook only until 175°F for a smooth custard. Refrigerate leftovers in a covered container up to 3 days; for best scoopable texture, let sit 5 minutes at room temperature before serving. Freezing is best—store up to 2 months. For a different dietary profile, use lactose-free milk and lactose-free cream in the same amounts.
