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 ↓
Gold Cake
Ingredients
Directions
The book says “a moderate oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the beaten egg yolks and mix well.
Stir in the cream of tartar and milk.
Gradually add the flour, orange or lemon juice, and baking soda. Mix until smooth and pour into a greased cake pan.
Bake
Bake slowly until a toothpick inserted in the center comes out clean.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Butter
- Adds fat and richness, giving the cake a tender crumb and flavor.
- Egg yolks
- Add richness, color and structure, helping the cake set and hold together.
- Flour
- Forms the cake's structure once its proteins set in the oven.
- Cream of tartar
- Acidifies the batter, stabilizing the egg proteins and helping the crumb stay fine.
- Baking soda
- Reacts with the acid in the batter to produce gas that helps the cake rise.
- Milk
- Adds moisture and liquid so the flour hydrates and the batter flows.
The step that matters
Bake slowly. A low oven temperature lets the cake rise and set gently without browning too fast or cracking on top. Baking until a toothpick comes out clean confirms the center has set, since an underbaked middle will sink as it cools.
Swap the orange
How well each one fits the dish's main ingredients (butter, sugar, egg, cream, milk, flour):

Fit is the average pairing score against butter, sugar, egg, cream, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
