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 ↓

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.

Add the beaten eggs and mix well.
Stir the baking soda into the sour milk and add to the mixture.
Gradually add the flour and mix until smooth.
Flavor with lemon to taste.
Bake and serve
Pour the batter into a small dripping pan.
Bake for 30 minutes.
Cut into squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to add richness and a tender crumb.
- Eggs
- Bind the batter and add structure as the cake sets.
- Baking soda
- Reacts with the sour milk to produce gas that leavens the cake.
- Sour milk
- Its acidity activates the baking soda and adds moisture.
- Flour
- Forms the structure that holds the cake together as it bakes.
The step that matters
Stir the baking soda into the sour milk and add to the mixture. Baking soda needs an acid to react and release carbon dioxide. Combining it with the sour milk before adding it to the batter lets the reaction happen in the mix, so the cake rises evenly rather than leaving dense or flat spots.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, butter, egg, milk, flour):

Fit is the average pairing score against sugar, butter, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
