How to make marshmallow swirl
Make the Ice Cream Base
Heat milk and cream in a saucepan over medium-high heat until gently simmering. Stir in vanilla, then remove from heat. Let steep for 30 minutes.
In a bowl, whisk egg yolks, sugar, and xanthan gum until pale and airy.
Slowly whisk the warm milk mixture into the yolks.
Return to low heat and cook, stirring constantly, until it thickens and reaches 170 to 180°F.
Cool to room temperature, then refrigerate for at least 2 hours or overnight.
Make the Marshmallow Swirl
Place egg whites and cream of tartar in a stand mixer bowl.
Combine water, sugar, and corn syrup in a saucepan. Heat without stirring until 240°F.
While the syrup heats, beat egg whites to soft peaks.
With the mixer on medium-low, slowly drizzle the hot syrup into the whites. Beat for 7 to 8 minutes until thick and glossy. Add vanilla and beat 1 more minute.
Assemble the Ice Cream
Churn the custard in an ice cream maker until thick but still soft.
Fold in 1 ½ cups marshmallow swirl, leaving visible streaks for that signature look.
Freeze in an airtight container for at least 4 hours before serving.
Toasted marshmallow swirl adds a smoky sweetness that pairs perfectly with graham crackers. Lightly torch sections of the swirl before folding it into the ice cream for a s’mores-inspired flavor. Want to switch things up? Add chopped salted almonds and melted milk chocolate along with the swirl for a rocky road version. Or sandwich scoops between graham crackers, dip in chocolate, and freeze for the ultimate s’mores ice cream sandwiches.
