In a medium saucepan, whisk together egg yolks, milk, sugar, and salt.
72 g egg yolks, 180 g whole milk, 80 g granulated sugar, 1 pinch of salt
Cook over medium heat, whisking constantly, until the mixture thickens and reaches 75–80°C (170–175°F).
Remove from heat and whisk in the freeze-dried strawberry powder until smooth.
12 g freeze dried strawberry powder
Stir in the heavy cream, 200 g of roasted strawberry purée, and vanilla extract (if using).
270 g heavy cream
Strain the mixture for extra smoothness, if desired.
Let cool slightly, cover, and chill for at least 4–6 hours, preferably overnight, until very cold.
Once the base is thoroughly chilled, pour it into your ice cream maker.
Churn according to your machine’s instructions (typically 20–25 minutes) until it reaches a soft-serve consistency.
Transfer to a freezer-safe container.
Cover and freeze for 2–4 hours until firm.
