Marshmallow sauce is one of those things that can’t be made in a small batch. It must be served the day it is made, so making it is a great excuse to feed the Caramel Coppetta with Marshmallow Sauce and Salted Spanish Peanuts (facing page) to a crowd.

Preparation
Step 1
Place the egg whites in the bowl of a standing mixer fitted with a whisk attachment and mix them on low speed until they form soft peaks.
Step 2
While the eggs are beating, fasten a candy thermometer to the side of a medium saucepan. Combine the sugar, corn syrup, and 1/2 cup of water in the saucepan and cook over high heat, brushing down the sides of the pot to remove the sugar crystals, for 5 to 8 minutes, until the temperature reads 231°F. Increase the mixer speed to high and continue to whip the whites until they form stiff peaks. Turn off the mixer until the sugar reaches 234°F. Return the mixer to high speed and pour the hot sugar syrup in a thin, steady stream along the sides of the bowl to combine it with the egg whites. When all of the syrup has been added, continue to beat until soft peaks form. Do not overwhip, or the marshmallow sauce will be too stiff. You want the sauce to be a spoonable consistency but not so loose that it is runny. Add the vanilla and beat to incorporate it. Transfer the marshmallow sauce to a medium bowl and set it aside to cool to room temperature before serving.
