How to make a Sobacha Sundae

01.

Make the Sobacha Ice Cream

Heat the cream, sobacha tea, and salt to 190°F.
In a separate bowl, whisk the egg yolks, then add the sugar and continue whisking until pale yellow.
Slowly temper the yolk mixture with the hot cream while whisking constantly.
Return the mixture to the pot and heat to 180°F.
Let the ice cream base rest overnight in the fridge.
Strain and spin the following day.

02.

Make the Okinawa Brown Sugar Caramel

Let the butter come to room temperature.
Combine both sugars, water, glucose, and salt in a saucepan and heat to 255°F.
Slowly add the cream, return to a boil, and whisk in the butter in small portions until smooth.

03.

Make the Tonka Bean Marshmallow

Heat the sugar, glucose, salt, tonka bean, and water to 240°F.
In a stand mixer fitted with a whisk attachment, beat the egg whites to soft peaks.
Bloom the gelatin.
Slowly stream the hot syrup into the egg whites while mixing on high.
Add the bloomed gelatin and continue mixing until the marshmallow is glossy and voluminous.

04.

Finish and Assemble

Scoop sobacha ice cream into a serving dish.
Spoon a layer of Okinawa brown sugar caramel over the base.
Top with a quenelle or toasted disc of tonka bean marshmallow.
Garnish with a dusting of grated tonka bean or edible gold if desired.
