Why it works: Milk and egg are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 88,785 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Maple Sugar Filling
Ingredients
Directions
Make the filling
Put the maple sugar into an agate saucepan and add the sweet milk.
Boil until it spins a thread.
Beat the egg whites until very stiff and gradually add the syrup while beating continuously.
Assemble
When the mixture thickens, quickly place it between the layers of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Maple sugar
- Provides the sweetness and maple flavour, and dissolves into a syrup when boiled with milk.
- Sweet milk
- Dissolves the maple sugar and carries it into a syrup for the filling.
- Egg whites
- Whipped to a stiff foam that gives the filling its light, airy body and thickening structure.
The step that matters
Beating the syrup into the egg whites. The whites must be very stiff before the hot syrup is added slowly while beating, so the foam holds its air. Adding the syrup too fast or to soft whites deflates the foam and leaves a dense filling.
