Why it works: Milk and butter 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 ↓
Starch Cake
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).
Dissolve the starch in sweet milk.
Make the batter
In a large bowl, cream together the butter and sugar.
Add the dissolved starch to the butter‑sugar mixture. Mix the mixture well.
In a separate bowl, beat the egg whites until stiff peaks form.
Fold the egg whites into the mixture gently.
Sift together the flour, baking powder, and salt.
Gradually add the sifted dry ingredients to the mixture.
Add flavoring to taste. Mix until just combined.
Bake
Pour the batter into a greased cake pan.
Bake for 30‑40 minutes or until a toothpick 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
- Eggs
- Whipped whites trap air, giving the cake lift and a light, airy crumb.
- Starch
- Starch absorbs moisture and sets during baking, giving the cake a tender, fine texture.
- Butter
- Fat coats flour particles and creams with sugar, adding richness and a tender crumb.
- Flour
- Flour provides the main structure as its proteins and starches set during baking.
- Baking powder
- Releases gas when heated, helping the batter rise in the oven.
The step that matters
Folding in the egg whites. Whipped whites are full of trapped air that the batter relies on for lift. Stirring them in vigorously knocks that air out, so the cake comes out dense; fold gently with a spatula until just combined.
