ROASTED BANANA ICE CREAM
Believe it or not, even people who say they don’t like bananas love this ice cream—it tastes just like banana bread pudding. We roast the bananas with dark brown sugar and butter until they are golden and caramelized, and then we fold them into our ice cream base. The ice cream that comes out is elegant and luscious, rich with caramelized bananas, and is one of our favorite winter flavors to make. The roasting of the bananas gives the ice cream such a creamy, almost burnt-caramel flavor; we can’t think of a better way to round out a Christmas dinner.
MAKES ABOUT 1 QUART
SPECIAL EQUIPMENT
Immersion blender
FOR THE ROASTED BANANAS
4 medium bananas, preferably somewhat speckled but not brown, peeled and cut into ¼-inch-thick slices
2 tablespoons (28 grams) unsalted butter
2 tablespoons (14 grams) dark brown sugar
Pinch of kosher salt
FOR THE ICE CREAM BASE
2 cups heavy cream
½ cup whole milk
¾ cup (150 grams) granulated sugar
½ teaspoon (2 grams) kosher salt
6 large egg yolks
1. To make the roasted bananas, preheat the oven to 400˚F; position the rack in the middle. Line a shallow baking sheet with parchment paper.
2. In a large bowl, toss the bananas, butter, sugar, and salt. Spread the ingredients on the prepared baking sheet and bake for 10 to 15 minutes, or until caramelized. Transfer to a cooling rack and let cool completely.
3. To make the roasted banana ice cream, pour the cream and milk into a double boiler or a heatproof bowl set over a saucepan of simmering water (the bottom of the bowl should not touch the water). Whisk in ½ cup (100 grams) of the sugar and the salt and stir until they have dissolved. Warm the mixture until you see steam rising from the top.
4. Meanwhile, prepare an ice bath in a large bowl and set another bowl over it. Set aside.
5. In a medium bowl, with a kitchen towel underneath it to prevent slipping, whisk together the egg yolks with the remaining ¼ cup (50 grams) sugar until uniform. While whisking, add a splash of the hot dairy mixture to the yolks. Continue to add the dairy mixture, whisking it in bit by bit, until you’ve added about half. Add the yolk mixture to the remaining dairy mixture in the double boiler. Set the heat under the double boiler to medium and cook the custard, stirring continuously with a wooden spoon and reducing the heat to medium-low as necessary, until steam begins to rise from the surface and the custard thickens enough to coat the back of the spoon. Hold the spoon horizontally and run your finger through the custard. If the trail left by your finger stays separated, the custard is ready to be cooled.
6. Strain the custard into the bowl sitting over the prepared ice bath and stir for 3 to 5 minutes, or until the custard has cooled. Transfer the custard to a quart-size container and add the roasted bananas. Using an immersion blender, buzz the custard until emulsified. Cover the custard and refrigerate for at least 4 hours or, preferably, overnight.
7. Pour the chilled custard into an ice cream maker and freeze according to the manufacturer’s instructions. Place the container in which you refrigerated the custard in the freezer so you can use it to store the finished ice cream. Churn the ice cream until the texture resembles “soft serve.” Transfer the ice cream to the chilled storage container and freeze until hardened to your desired consistency. Alternatively, you can serve it immediately—it will be the consistency of gelato. The ice cream will keep, frozen, for up to 7 days.
ben’s note Keep in mind that bananas will vary in size and moisture content, depending on the season, country of origin, humidity levels in your environment, just to name a few. When dealing with fruit—and we’ll say it again and again in this book—you’re bound to get diff ering results, as fruit itself will always vary.
