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 slow oven”. The 300°F (150°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 300°F (150°C).
Cream together the sugar and butter until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
In a separate bowl, combine the flour, cream of tartar, and baking soda.
Make the batter
Gradually add the dry ingredients to the creamed mixture, alternating with the sweet milk.
Mix until smooth and well combined.
Pour the batter into a greased cake pan.
Bake
Bake in the slow oven for about 30-40 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Add structure and richness, binding the batter as they set in the oven.
- Butter
- Adds fat and tenderness, and creaming it traps air for a lighter crumb.
- Flour
- Forms the cake's structure as its proteins set during baking.
- Cream of tartar
- Acidifies the batter and helps the baking soda produce lift.
- Baking soda
- Reacts with the acid in the batter to release gas, helping the cake rise.
- Sugar
- Sweetens the cake and helps create a soft, tender texture when creamed.
The step that matters
Adding the dry ingredients alternately with the milk. Adding flour in portions alternated with liquid keeps the batter smooth and prevents overmixing. Overmixing develops too much gluten, which can make the cake tough.
