Method
Make the vanilla base
- Heat the heavy cream and whole milk until steaming. Visual cue: small bubbles and steam rise from the surface.
- Whisk the hot cream mixture into the egg yolks beaten with 1/2 cup granulated sugar. Visual cue: the custard mixture turns smooth and slightly thickens.
- Return to heat and cook until the custard reaches 175F, whisking to prevent scorching. Time range: about 5 minutes; visual cue: it coats the back of a spoon.
- Strain the custard into a clean bowl. Visual cue: a smooth, lump-free texture without any egg bits.
- Stir in vanilla extract and salt, then cool completely. Visual cue: the mixture cools to room temperature before chilling.
Make the orange syrup
- Combine fresh orange juice, orange zest, and the remaining 1/4 cup granulated sugar in a small saucepan. Visual cue: the sugar dissolves as the liquid warms.
- Simmer for 5 minutes until slightly syrupy, then cool completely. Visual cue: it looks glossy and coats a spoon lightly.
Churn and swirl
- Churn the vanilla custard in an ice cream maker until thick. Visual cue: it looks like soft-serve and holds peaks.
- In the last 2 minutes, drizzle in the orange syrup to create swirls, and do not fully mix. Visual cue: distinct orange streaks remain.
Layer and freeze
- Transfer to a container, layering spoonfuls while keeping the swirl pattern. Visual cue: a marbled orange-and-vanilla look on the surface.
- Freeze at least 4 hours. Visual cue: the ice cream becomes firm enough to scoop cleanly.
Notes
Pro tip: cool both the vanilla custard and the orange syrup completely before churning so the mixture thickens evenly and the swirls stay vivid. Store covered in the freezer for up to 2 weeks; freezer yes. For a lighter option, use half-and-half in place of some heavy cream, which will make the texture slightly softer.
