What each ingredient does
- Maple molasses
- Provides the sweetness and rich maple flavour, and body once boiled down.
- Egg white
- Beaten into the hot syrup, it adds structure and lightens the filling as it thickens.
The step that matters
Slowly stir in the well-beaten egg white.. The syrup is hot, so adding the egg white quickly can cook it into lumps. Pouring slowly while stirring spreads the heat evenly and keeps the egg white smooth.
