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 ↓
Chocolate Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and gradually add the sugar.
Mix in the milk and flour that has been sifted with the baking soda and cream of tartar.
Beat the egg whites and fold them into the mixture.
Add the grated chocolate and mix thoroughly.
Bake and finish
Bake for 45 minutes at 350°F (175°C).
When the cake is removed from the pan and still hot, cover the bottom with halved marshmallows, sticky side down.
Coat the entire cake with chocolate water icing.

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 lightness and a open, airy crumb.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Sugar
- Sweetens the cake and helps tenderise the crumb while creaming with butter.
- Butter
- Adds fat for richness and a tender texture.
- Baking soda
- Reacts with cream of tartar to produce gas that helps the cake rise.
- Cream of tartar
- Acid that reacts with baking soda to release gas, aiding rise and stabilising the whites.
The step that matters
Folding in the egg whites. Egg whites hold air only when beaten to the right stiffness. Folding gently keeps that air in the batter; stirring vigorously would deflate it and leave a denser cake.
“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.
