Plantain Caramel Swirl Ice Cream

Steps

1. 1

   Prepare plantain puree

   • Peel 2 ripe plantains and cut into 1-inch (2.5 cm) chunks.
   • Bring a large pot of salted water to a boil over high heat.
   • Add plantain chunks and boil for 12–15 minutes until very tender when pierced with a fork (the internal flesh should be soft and offer no resistance).
   • Drain thoroughly in a colander, pressing gently to remove excess water.
   • Transfer drained plantains to a blender or food processor and puree until completely smooth, about 1–2 minutes.
   • Pour the puree through a fine-mesh sieve, using a rubber spatula to gently press the puree through and leave behind any fibrous strands (this step is optional but recommended for a silkier texture).
   • Transfer the strained puree to a bowl and let cool to room temperature, stirring occasionally, about 10–15 minutes.
   • Use immediately or cover and refrigerate until needed (can be made up to 1 day ahead).

   Ready when: Plantains are very soft and tender when pierced; puree is smooth with no lumps or fibers visible

   Tip: Straining through a sieve removes the fibrous texture for a silkier, more refined ice cream. Don't skip this step if you want smooth, velvety results.

2. 2

   Whisk eggs and sugar

   • While the plantains cool, place 6 large egg yolks and 1/2 cup (100 g) granulated sugar in a medium mixing bowl.
   • Whisk vigorously for 2–3 minutes until the mixture is pale yellow and thickened, leaving a distinct ribbon trail when you lift the whisk out of the bowl.
   • This aeration helps create a stable emulsion for the ice cream.

   Ready when: Mixture is pale yellow, thick, and ribbons from the whisk when lifted

   Tip: Room-temperature eggs whisk more easily and incorporate air better than cold eggs, giving you better results.

3. 3

   Heat cream and milkOven 170°F / 75°C

   • Combine 2 cups (480 ml) heavy cream and 1 cup (240 ml) whole milk in a medium heavy-bottomed saucepan.
   • Heat over medium heat, stirring occasionally, until the mixture is steaming and reaches about 170°F (77°C) on a thermometer.
   • Do not let it boil—you want it very hot and steamy but still below the boiling point.
   • Small wisps of steam should rise from the surface, but no bubbles should form at the edges.

   Ready when: Thermometer reads 170°F (77°C); steam rises from surface; no bubbles at the edges

   Tip: If you don't have a thermometer, the mixture is ready when wisps of steam rise and the surface is too hot to touch comfortably. Watch carefully to avoid overheating.

4. 4

   Temper eggs and cook custardOven 160°F / 70°C

   • Remove the hot cream mixture from heat and let it cool for 30 seconds.
   • Very slowly pour the hot cream into the whisked eggs while whisking constantly to avoid scrambling the yolks.
   • Once all the cream has been incorporated, pour the entire mixture back into the saucepan.
   • Place the saucepan over medium heat and cook, stirring constantly with a rubber spatula (scraping the bottom and sides continuously) to ensure even cooking.
   • Cook until the custard reaches 160°F (71°C) on a thermometer and coats the back of a spoon (dip a spoon, draw your finger across it, and if it leaves a trail without the mixture filling back in, it's done).
   • This should take 8–10 minutes.
   • Remove from heat immediately.
   • Stir in 1 tsp vanilla extract, 1/4 tsp salt, and 1/4 tsp cinnamon (if using).

   Ready when: Custard reaches 160°F (71°C) on thermometer; coats back of spoon without filling in; steam rises gently

   Tip: Keep the heat at medium and stir constantly to prevent scrambling. If you see any cooked egg particles forming, immediately remove from heat and strain through a fine sieve.

5. 5

   Strain and chill custard

   • Pour the hot custard through a fine-mesh sieve into a clean medium bowl, pressing gently to ensure all liquid passes through while leaving any cooked egg particles or lumps behind.
   • Let the strained custard cool to room temperature, stirring occasionally, for about 15–20 minutes.
   • Once cooled to room temperature, press plastic wrap directly onto the surface of the custard to prevent a skin from forming, then cover the bowl and refrigerate for at least 4 hours, or preferably overnight.
   • The custard must be thoroughly chilled and cold to the touch before churning.

   Ready when: Custard is completely chilled and no longer warm to the touch

   Tip: Chilling overnight actually improves flavor development. The minimum chill time is 4 hours, but overnight is better and will give you superior results.

6. 6

   Fold in plantain puree

   • Remove the chilled custard from the refrigerator.
   • Using a rubber spatula, gently fold the cooled plantain puree (about 1 cup / 240 ml) into the custard using broad, gentle strokes until evenly combined with no white custard streaks or orange plantain streaks remaining.
   • The mixture should be a uniform pale yellow-beige color throughout.

   Ready when: Plantain puree is completely and evenly combined with custard; no white or orange streaks visible

   Tip: Use gentle folding motions rather than vigorous stirring to combine the ingredients and preserve the texture of the chilled custard.

7. 7

   Make caramel sauce

   • In a small heavy-bottomed saucepan, combine 1/4 cup (50 g) granulated sugar and 3 tbsp (45 ml) water.
   • Heat over medium-high heat without stirring (if needed to combine, swirl the pan gently).
   • Once the sugar is fully dissolved, stop swirling and let it cook undisturbed for 3–5 minutes.
   • The sugar will begin to turn golden around the edges.
   • Continue cooking and occasionally swirl the pan gently while watching carefully.
   • When the caramel reaches a deep amber color (similar to dark brewed iced tea), about 2–3 minutes more, remove the pan from heat immediately.
   • The caramel should smell rich and toasty, not burnt.
   • Let cool for 1 minute.
   • Add 2 tbsp (30 g) cold unsalted butter and stir until melted and fully incorporated.
   • Slowly add 1/4 cup (60 ml) heavy cream in a thin stream while stirring (the mixture will bubble and steam vigorously for a moment—this is normal and expected).
   • Stir until completely smooth and homogeneous.
   • Add a pinch of salt and stir to combine.
   • Transfer to a bowl and let cool to room temperature, stirring occasionally, about 30 minutes.
   • The sauce will thicken as it cools.

   Ready when: Caramel is deep amber color (like dark iced tea); mixture is smooth and homogeneous after cream is added

   Tip: Watch the caramel carefully once it starts to brown—it can go from perfect to burnt in seconds. Don't stir the sugar while it dissolves and cooks, as this can cause crystallization.

8. 8

   Churn ice cream

   • Remove the chilled plantain-custard mixture from the refrigerator.
   • Verify that your ice cream maker bowl has been pre-chilled per the manufacturer's instructions (usually overnight or at least 4 hours in the freezer).
   • Pour the plantain custard into the pre-chilled ice cream maker bowl and churn according to your machine's instructions.
   • Most machines will churn for 20–30 minutes until the ice cream reaches a soft-serve consistency.
   • The ice cream should hold peaks when the dasher is lifted out but still be pourable and creamy—not quite solid, but noticeably thicker and fluffier than the original mixture.

   Ready when: Ice cream reaches soft-serve consistency, holding peaks when paddle is lifted but still creamy and pourable

   Tip: Most ice cream makers have a removable paddle or dasher; ice cream should stick to it when you lift it out. Follow your specific machine's guidelines for doneness.

9. 9

   Swirl caramel and freeze

   • Transfer the churned ice cream to a freezer-safe container with at least 1.5-quart (1.4 L) capacity.
   • Drizzle the cooled caramel sauce over the surface of the ice cream in thin, irregular streams.
   • Using a spatula, spoon handle, or butter knife, gently drag through the ice cream to create swirls, being careful not to fully blend the caramel throughout—you want distinct ribbons and pockets of caramel, not evenly distributed throughout.
   • Cover the container with plastic wrap, then seal with the container's lid.
   • Place in the freezer and freeze until the ice cream is completely firm, at least 4 hours or overnight.

   Ready when: Ice cream is solid and holds its shape when scooped; caramel ribbons are visible and distinct

   Tip: Freezing overnight improves flavor development and texture. If you need to serve sooner, 4 hours is the minimum, but the ice cream may be slightly softer than ideal.
