Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Chocolate Cake
Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the cake
Preheat the oven to 350°F (175°C).
Cream together the butter and sugar until light and fluffy.
Add the sweet cream, egg yolks, and whole egg, mixing well.
In a separate bowl, combine the flour, cream of tartar, and baking soda (or baking powder).
Gradually add the dry ingredients to the wet mixture, stirring until smooth.
Pour the batter into greased jelly cake tins and bake until a toothpick comes out clean.
Make the icing and finish
For the icing, melt the chocolate in a bowl over boiling water.
In another bowl, beat the egg whites until stiff, then gradually add the sugar.
Fold the melted chocolate into the egg white mixture and spread over the cooled cakes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving the cake a light, tender crumb and rich flavor.
- Egg yolks
- Add richness, moisture and structure as they set during baking.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Cream of tartar
- Acidifies the batter so the leavener reacts well, helping the cake rise and stay tender.
- Baking soda
- Reacts with the acidic ingredients to produce gas that makes the cake rise.
- Egg whites
- Beaten until stiff to build a light, airy foam that lightens the icing.
The step that matters
Folding the melted chocolate into the egg whites. Stirring vigorously deflates the whipped egg whites, which lose the air that keeps the icing light. Gentle folding preserves the foam so the icing stays airy and spreadable.
