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 ↓
Ginger Bread
Ingredients
Directions
Make the dough
In a large bowl, mix sugar, butter, sour milk, baking soda, alum, and ground ginger.
Gradually add flour until the mixture is as stiff as cookie dough.
Keep the dough in a cool place until ready to bake.
Bake and serve
Roll the dough to about 1 inch thick, the size of a bread pan.
Bake until golden brown, then cut into squares and serve warm.

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
- Sugar
- Adds sweetness and helps the crust brown during baking.
- Butter
- Adds fat for richness and a tender texture.
- Sour milk
- Provides moisture and acidity that react with the baking soda.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lifts the dough.
- Flour
- Forms the structure that makes the dough stiff enough to roll.
The step that matters
Gradually add flour until the mixture is as stiff as cookie dough. Flour absorbs liquid and builds structure. Adding it gradually lets you judge the stiffness, since too much flour makes the gingerbread dry and dense while too little leaves it sticky and hard to roll.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, butter, milk, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Gingerthe original
Fit is the average pairing score against sugar, butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
