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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Sift the flour into a deep pan and rub in the butter.
Mix in the powdered sugar and ground ginger.
Beat the eggs until light and gradually mix them with the other ingredients.
Dissolve the pearl ash in the sour milk and add it to the mixture.
Stir the mixture vigorously until well combined.
Shape and bake
Flour a surface and roll out the dough to 1 inch thick, adding more flour if necessary.
Grease a large shallow square pan and place the dough in it.
Bake in a moderate oven at 350°F (175°C) until cooked through.
Once cooled, cut into squares or use a jagging iron to cut out separate cakes.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 main structure that holds the dough together as it bakes.
- Unsalted butter
- Rubbed into the flour to add richness and a tender, crumbly texture.
- Powdered white sugar
- Adds sweetness and dissolves easily into the dough for a fine, even crumb.
- Eggs
- Add structure and richness, binding the dough as they are mixed in.
- Pearl ash
- Dissolved in sour milk to release gas, helping the dough rise and lighten.
- Sour milk
- Its acidity activates the pearl ash and adds moisture and tang.
The step that matters
Dissolving the pearl ash in the sour milk. Pearl ash is an alkaline leavener that needs an acid to react. Fully dissolving it in the sour milk lets the reaction spread evenly, so the cake rises without patches or a soapy, bitter taste.
Swap the ginger
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, milk):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Gingerthe original
Fit is the average pairing score against flour, butter, sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
