Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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 batter
Preheat your oven to 350°F (175°C).
In a mixing bowl, cream together the butter and sugar.
Add the milk and eggs, and mix well.
In a separate bowl, combine the baking soda and cream of tartar with the flour.
Gradually add the flour mixture to the wet ingredients until the batter is thick like pound cake.
Bake
Divide the batter between two pie pans and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to add richness and a tender crumb.
- Sugar
- Sweetens the cake and helps brown the crust while creaming with the butter.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Baking soda
- Reacts with the cream of tartar to release gas that lifts the batter.
- Cream of tartar
- Acid that works with the baking soda to help the cake rise.
- Flour
- Forms the structure of the batter that sets in the oven.
The step that matters
Gradually add the flour mixture to the wet ingredients. Adding flour gradually and mixing only until combined keeps the batter smooth and prevents overdeveloped gluten, which would make the cake tough. The batter should be thick like pound cake, so the rising agents can lift it evenly.
