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 ↓
A Good Soda 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 the batter
Preheat the oven to 350°F (175°C).
In a large bowl, break the butter into the flour.
Mix in the sugar.
Add the boiling milk and well-beaten eggs.
Stir in the nutmeg, finely shredded candied peel, and currants.
Beat the mixture well together.
Stir in the baking powder and beat the batter for a few more minutes.
Bake
Pour the batter into a buttered mold and bake for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Adds fat for tenderness and a rich texture in the crumb.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Baking powder
- Releases gas during baking so the batter rises and becomes light.
- Milk
- Adds moisture and helps dissolve the sugar into the batter.
- Currants
- Add pockets of sweetness and chew throughout the cake.
The step that matters
Stir in the baking powder and beat only a few minutes. Baking powder starts releasing gas as soon as it gets wet and heated, so the batter should go into the mold promptly. Overbeating after it is added can knock out gas and leave the cake denser.
Swap the currant
