Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, mix the sugar, milk, and eggs until well combined.
Add the flour and baking powder, and stir until smooth.
Pour the batter into greased sandwich tins.
Bake and assemble
Bake until golden brown, about 25-30 minutes.
Once cooled, spread preserves between the layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and lift when combined with the batter, and add moisture and richness.
- Flour
- Forms the structure of the sponge as its proteins and starches set during baking.
- Sugar
- Adds sweetness, tenderness, and helps the crust brown.
- Baking powder
- Releases gas in the batter, making the sponge rise and become light.
- Milk
- Adds moisture and helps the batter blend into a smooth, tender crumb.
The step that matters
Stir the flour in until just smooth. Once flour is added, mixing develops gluten in the batter. Overmixing makes the sponge tough and dense, so stop as soon as the batter is smooth.
