Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Sugar 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.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a large bowl, cream together the sugar and butter until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Dissolve the hartshorn in the water and add it to the mixture.
Gradually add flour until the batter reaches a workable consistency.
Bake
Pour the batter into prepared baking pans and bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the cake and helps it brown while creaming with butter adds air.
- Butter
- Adds fat and richness, and creaming it with sugar traps air for a lighter crumb.
- Eggs
- Add structure and richness, and help bind the batter as it sets in the oven.
- Hartshorn
- Releases gas as it breaks down, helping the cake rise.
- Flour
- Provides the structure that sets the batter as it bakes.
The step that matters
Adding the eggs one at a time. Adding eggs gradually lets each one emulsify fully into the creamed butter and sugar. Adding them too fast can cause the mixture to curdle, which can make the cake's texture coarse and uneven.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
