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.
Make the sponge
Preheat your oven to 350°F (175°C).
In a bowl, mix 1 cup sugar, 2 eggs, 1½ cups flour, 4 tablespoons water, ½ teaspoon baking soda, and 1 teaspoon cream of tartar until smooth.
Pour the mixture into a pie dish and bake until set.
Make the cream and assemble
For the cream, combine 2 cups milk, 1 cup sugar, and 2 tablespoons flour in a saucepan over medium heat.
Stir until thickened, then remove from heat.
Fill the pie with the cream while warm and let it cool in a cool place.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and richness as they set the batter into a light, tender sponge.
- Flour
- Forms the structure of the sponge and thickens the cream as it cooks.
- Milk
- Forms the liquid base of the cream, which thickens as it heats with the flour.
- Sugar
- Sweetens the sponge and the cream, and helps the cream thicken with the flour.
- Baking soda
- Reacts with the cream of tartar to produce gas that helps the sponge rise.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda, helping the sponge rise and stay tender.
The step that matters
Stir the cream until thickened. Flour thickens milk only when it is stirred over heat long enough for the starch to swell. Stopping too early leaves a thin filling that will not hold between the layers, while overcooking can scorch the milk on the bottom of the saucepan.
