Coquito Frozen Custard

Steps

1. 1

   Heat cream and milkOven 170°F / 75°C

   • Combine the 2 cups cold heavy cream and 1 cup cold whole milk in a medium saucepan (2–3 quart capacity).
   • Set over medium heat and stir occasionally.
   • Heat until the mixture is steaming and registers about 160–170°F (71–76°C)—it should be very hot but not boiling, with small bubbles forming around the edges.
   • This takes 10–13 minutes.

   Ready when: Mixture steams and reaches 160–170°F (71–76°C); tiny bubbles form at the edges but mixture does not boil.

   Tip: Stir occasionally to ensure even heating and prevent a skin from forming on the surface.

2. 2

   Whisk eggs and sugar

   • While the cream heats, place the 6 room-temperature egg yolks in a large mixing bowl.
   • Add the 3/4 cup granulated sugar.
   • Whisk by hand or with an electric mixer on medium speed for 2–3 minutes, until the mixture is pale, thick, and ribbons form when you lift the whisk.

   Ready when: Mixture is pale, thick, and voluminous; ribbons form when you lift the whisk, and the volume has roughly tripled.

   Tip: Use room-temperature eggs, as cold eggs are harder to whisk into a pale, voluminous mixture.

3. 3

   Temper egg yolks

   • With the hot cream and milk ready, slowly drizzle it into the egg and sugar mixture while whisking constantly.
   • Start with just a few tablespoons to gently raise the temperature of the eggs, then add the rest in a thin, steady stream while whisking vigorously.
   • This tempering process should take about 2–3 minutes and prevents the eggs from scrambling.

   Ready when: Mixture is smooth, homogeneous, and pale; no streaks of hot cream or egg remain.

   Tip: Pour the hot cream slowly and steadily; rushing this step can result in scrambled eggs instead of a smooth custard.

4. 4

   Cook custard to donenessOven 165°F / 75°C

   • Pour the combined mixture back into the saucepan and set it over medium-low heat.
   • Stir constantly with a whisk or wooden spoon, scraping the bottom and sides to prevent sticking.
   • Cook until the custard coats the back of a spoon (when you dip the spoon in and run your finger across the back, a clear trail remains) and an instant-read thermometer reads 160–165°F (71–74°C).
   • This takes 8–12 minutes.
   • Do not allow it to boil or simmer vigorously.

   Ready when: Custard coats the back of a spoon with a clear trail when wiped; instant-read thermometer reads 160–165°F (71–74°C).

   Tip: Stir constantly to prevent the bottom from overheating; an undercooked custard is unsafe, but overcooked custard becomes lumpy.

5. 5

   Strain and cool

   • Remove the saucepan from heat.
   • Set a fine mesh strainer over a medium mixing bowl and carefully pour the hot custard through the strainer, which catches any lumps or cooked egg solids.
   • Let the custard cool at room temperature for 5–10 minutes, stirring occasionally.

   Ready when: Custard has cooled to about 100–110°F (38–43°C) and is warm but can be touched without discomfort.

   Tip: Straining removes any cooked egg solids and ensures a silky-smooth final texture.

6. 6

   Stir in rum and spices

   • Once the custard has cooled slightly, whisk in the 1/2 cup coconut cream until fully blended.
   • Add the 1/2 cup light or dark rum, 2 tsp vanilla extract, 1.5 tsp ground cinnamon, and 3/4 tsp ground nutmeg.
   • Whisk thoroughly for about 1 minute until the spices are evenly distributed and there are no visible streaks or clumps.
   • The mixture will have a warm, spiced aroma.

   Ready when: Mixture is smooth and uniformly colored; spices are fully incorporated with no visible clumps or streaks.

   Tip: Whisk thoroughly to avoid spice clumps that can settle during churning and not blend smoothly into the frozen custard.

7. 7

   Chill custard base

   • Cover the bowl with plastic wrap or a lid.
   • For best results, refrigerate for at least 4 hours, or preferably overnight (up to 24 hours), which allows flavors to meld and improves the final texture.
   • If time is limited, cool the custard in an ice bath (a large bowl nested in another bowl filled with ice and water) for 30–45 minutes, stirring occasionally, until the mixture is very cold (below 40°F / 4°C).

   Ready when: Custard is very cold (below 40°F / 4°C) and thick; when dipped with a spoon, it drops slowly and heavily.

   Tip: A well-chilled custard churns more efficiently and produces a denser, creamier texture; do not skip this step.

8. 8

   Churn in ice cream maker

   • Remove the custard from the refrigerator and pour it into your ice cream maker with the chilled bowl.
   • Churn according to your machine's instructions, typically 20–30 minutes.
   • The mixture will transform from liquid to soft-serve consistency, lightening slightly in color and thickening noticeably.
   • You'll hear the motor working harder as the mixture becomes stiffer.
   • Stop churning when it resembles soft-serve ice cream and is no longer freely pourable.

   Ready when: Mixture reaches soft-serve consistency—noticeably thickened and lighter in appearance; the machine labors audibly.

   Tip: Do not over-churn; once it resembles soft-serve, stop immediately or it may become grainy or overly dense.

9. 9

   Freeze to firm texture

   • Transfer the churned custard to a freezer-safe airtight container (1-quart / 1-liter capacity).
   • If desired, fold in the 1/4 cup toasted coconut flakes at this point.
   • Cover tightly with a lid or plastic wrap and freeze for at least 8 hours, or until it reaches a firm, scoopable texture.
   • It will harden further over the next few hours as the churned air sets and additional ice crystals form.

   Ready when: Custard is hard enough that a spoon requires firm pressure to scoop; it should not fall apart or crumble when scooped, but also not be rock-hard.

   Tip: If frozen solid and difficult to scoop, let the container sit at room temperature for 5–10 minutes before scooping to soften slightly.
