Gelato / Sorbetto Recipe

Prepare infusion

Split the vanilla bean lengthwise and scrape the seeds into a saucepan. Add the pod, whole milk, and heavy cream. Warm over medium heat until it just begins to steam and small bubbles form at the edges (do not boil). Remove from heat, cover, and let steep 20–30 minutes for maximum flavor.

Make custard

In a medium bowl, whisk the egg yolks with the granulated sugar until pale and slightly thickened. Warm the infused milk again gently. Slowly temper about 1/3 cup of the warm milk into the yolks while whisking constantly, then slowly pour the yolk mixture back into the saucepan with the remaining milk, whisking to combine.

Cook to nappe

Return the saucepan to low–medium heat and cook, stirring constantly with a wooden spoon or spatula and scraping the bottom, until the mixture thickens slightly and coats the back of the spoon (nappe) — about 170–175°F (76–80°C). Do not boil.

Finish and chill

Remove from heat. Strain the custard through a fine-mesh sieve into a clean bowl to remove the vanilla pod and any cooked bits. Stir in the inverted sugar (or corn syrup) and salt. If using vanilla extract instead of a bean, stir it in now (about 1 tsp). Cool to room temperature, then cover and refrigerate until thoroughly chilled, at least 4 hours or overnight.

Churn and freeze

When chilled, pour the custard into a pre-chilled ice cream machine and churn according to the manufacturer's instructions until it reaches a soft-serve consistency (about 20–30 minutes). If adding mix-ins (nuts, chocolate chips), fold them in during the last 2–3 minutes of churning. Transfer to an airtight container, press a piece of plastic wrap on the surface to prevent ice crystals, and freeze at least 2 hours to firm up before serving.

Make syrup

In a saucepan combine the water and granulated sugar. Add the lemon zest. Warm over medium heat, stirring until the sugar fully dissolves. Bring just to a very light simmer for 1–2 minutes to infuse the zest, then remove from heat and let steep for 10–15 minutes.

Strain and combine

Strain the syrup into a bowl to remove the zest. Stir in the lemon juice, glucose or corn syrup (if using), and a pinch of salt. Taste and adjust sweetness or acidity — the mixture should taste slightly sweeter than the finished sorbet because freezing dulls acidity and sweetness.

Chill

Chill the lemon mixture thoroughly in the refrigerator until cold, at least 2 hours. For best texture, chill until very cold.

Churn and finish

Pour the chilled lemon mixture into a pre-chilled ice cream machine and churn according to the manufacturer's instructions until it reaches a smooth, scoopable sorbet texture (about 15–25 minutes). If using fruit purée, fold it in during the last few minutes of churning for a swirled effect. Transfer to an airtight container and freeze for at least 1–2 hours to set before serving. Hold the finished sorbet in the freezer and serve slightly softened (5–10 minutes at room temperature) for best scoopability.

For gelato: fold in toasted nuts, chocolate chips, or swirl fruit purée during the last 2–3 minutes of churning or immediately after churning before final freeze. For sorbetto: fold in fresh berry purée for flavor or ripple after churning. For presentation: garnish with fresh mint, a grating of lemon zest (for sorbet), or a light dusting of cocoa (for chocolate gelato) just before serving.
