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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the milk.
In a separate bowl, combine the flour, cream of tartar, and baking soda.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Pour the batter into a greased cake pan.
Bake
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and add richness and tenderness.
- Sugar
- Creams with butter for a light texture and adds sweetness and browning.
- Eggs
- Add structure and binding so the batter holds together as it bakes.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
- Cream of tartar
- Acidifies the batter so the baking soda reacts and helps the cake rise.
- Baking soda
- Reacts with the acid in the batter to produce gas that makes the cake rise.
The step that matters
Mixing the dry ingredients into the wet mixture. Gradually adding dry ingredients and mixing only until combined limits gluten development, keeping the cake tender rather than tough. Overmixing toughens the batter and can make the rise uneven.
