Why it works: Cocoa and chocolate work together. They rank in the top 9% of all ingredient pairs, and cooks put them together in 165 recipes. Both carry 2-ethyl-3,6-dimethylpyrazine, which smells roasted, nutty. The science ↓
Chocolate Cake
Ingredients
Directions
Make the cake batter
Cream one-half cup butter and one and one-half cups sugar.
Add the yolks of three eggs, three tablespoons cocoa, one cup water, and two cups flour.
Add the whites of three eggs that have been beaten for ten minutes.
Flavor with vanilla and mix in two teaspoons Royal Baking Powder just before placing in oven.
Use two squares of chocolate instead of cocoa if preferred.
Make the filling
For the filling, combine one cup water, one-half cup sugar, two teaspoons corn starch, two teaspoons cocoa, and vanilla.
Cook the filling.
Assemble and finish
Put the filling between the cake layers and ice the cake with plain white icing.
Nutrition, whole recipe (rough)
Counts 5 of 6 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 5 portions
| Ingredient | Portion assumed | kcal |

| Chocolate | 1 oz (28g) semisweet | 155 |
| Butter | 1 tbsp (14g) | 102 |
| Egg | 1 large egg (50g) | 78 |
| Sugar | 1 tbsp (12.5g) granulated | 49 |
| Water | not in our table | 0 |

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
- Whites beaten separately add air and lift, giving the cake a light, open crumb.
- Flour
- Provides the starch and structure that set the cake's crumb as it bakes.
- Butter
- Creamed with sugar, it traps air and adds richness and tenderness.
- Baking powder
- Releases gas when heated, causing the batter to rise in the oven.
- Cocoa
- Adds chocolate flavor and deep color to the cake and filling.
- Sugar
- Sweetens the cake and helps create a tender texture when creamed with butter.
The step that matters
Mix in the baking powder just before placing in oven. Baking powder starts releasing gas as soon as it is wet and heated, so the batter should go into the oven right after mixing to keep the rise strong.
Swap the cocoa
How well each one fits the dish's main ingredients (butter, flour, chocolate, sugar, corn, egg):
- Almondfits better
- Hazelnutfits better
- Macadamia nutfits better
- Cocoathe original
Fit is the average pairing score against butter, flour, chocolate, sugar, corn, egg. Candidates are from the same food group and used in at least 100 recipes.
