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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Mix the batter
In a large bowl, rub the butter into the flour and sugar until well combined.
Add the beaten eggs and warm milk to the mixture.
Dissolve the baking soda in the milk and mix it in.
Combine all ingredients thoroughly and pour into a baking pan.
Bake
Bake for 2 hours until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the cake together as it sets.
- Moist sugar
- Adds sweetness, moisture and a deep caramel flavor and browning.
- Butter, lard, or dripping
- Adds fat that tenderizes the crumb and carries flavor.
- Large eggs
- Bind the batter and help set its structure during baking.
- Baking soda
- Reacts with the milk to produce gas that lifts and aerates the cake.
The step that matters
Dissolve the baking soda in the milk. Baking soda must be fully dissolved so it reacts evenly throughout the batter. Undissolved pockets can leave bitter spots or uneven rising, and the milk should be warm, not hot, so the reaction proceeds steadily rather than too quickly.
“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.
