Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Washington Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare and bake
Preheat the oven to 350°F (175°C).
In a bowl, mix sugar, flour, cold water, and baking powder until smooth.
Pour the batter into a loaf pan and bake until golden brown.
Assemble
Once cooled, cut the top off the cake thinly and remove some of the center.
Fill the hollow with whipped cream, sweetened and flavored to your liking.
Fold the beaten egg whites into the cream before filling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the starch and gluten network that gives the cake its structure.
- Baking powder
- Releases gas as it reacts with heat, lifting the batter so the cake rises.
- Sugar
- Sweetens the cake and helps its surface turn golden brown as it bakes.
- Egg whites
- Beaten whites trap air, adding lightness to the cream filling.
- Whipped cream
- Adds moisture and richness to the filling, sweetened to taste.
The step that matters
Folding the beaten egg whites into the cream. Beaten egg whites hold air in a foam. Folding gently, rather than stirring, keeps that air in the cream so the filling stays light instead of deflating.
