What each ingredient does
- Whites of 4 eggs
- Whipped into a foam, the proteins trap air and form the light, stable structure of the filling.
- Marshmallows
- Add sweetness and body, softening into the warm foam to make it thick and chewy.
The step that matters
Add the marshmallows as soon as the syrup goes in. Hot syrup softens the marshmallows so they blend into the warm foam. If the mixture cools and stiffens first, the marshmallows will not incorporate evenly.
