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.
Make the batter
Beat the butter to a light cream, gradually adding the sugar until very light.
Add the ginger and dissolved baking soda.
Pour in the sour milk and stir in enough flour to make a batter that is just stiff enough not to run off the baking sheet.
Bake and cut
Butter the baking sheets evenly and spread the batter thinly like a wafer.
Bake in a moderate oven at 350°F (175°C) until a clear brown.
Once removed from the oven, cut into squares while still hot using a thin knife.

Butter and flour 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
- Butter
- Creams with the sugar to add richness and a tender, crisp texture.
- Sugar
- Sweetens the batter and helps it brown as it bakes.
- Baking soda
- Reacts with the sour milk to lighten the batter and help it spread and crisp.
- Sour milk
- Its acidity activates the baking soda and adds moisture and tang.
- Flour
- Provides the structure that holds the thin batter together after baking.
The step that matters
Spread the batter thinly. A thin, evenly spread layer bakes through and turns crisp; thick spots stay soft and may not brown evenly. Stiffness keeps the batter from running off the sheet.
Swap the ginger
How well each one fits the dish's main ingredients (butter, sugar, milk, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Gingerthe original
Fit is the average pairing score against butter, sugar, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
