Why it works: Flour and buttermilk are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Hard Ginger Cake
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make and shape the dough
In a large bowl, mix the flour, sugar, molasses, butter, ground ginger, baking soda dissolved in buttermilk until well combined.
Roll out the dough thinly on a floured surface.
Cut into desired shapes and place on a baking sheet.
Bake
Bake in the preheated oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the dough together and lets it be rolled and cut.
- Molasses
- Adds moisture, sweetness and a deep colour that helps the cake brown.
- Butter
- Adds fat, which tenderises the dough and adds richness to the cake.
- Baking soda
- Reacts with the acidity in the buttermilk to produce gas that lightens the dough.
- Ground ginger
- Provides the main spicy aroma and flavour of the cake.
- Buttermilk
- Adds acidity to activate the baking soda and contributes moisture to the dough.
The step that matters
Rolling the dough thinly. Thin dough bakes through and crisps evenly, while thicker dough can stay soft in the centre and brown unevenly before the middle sets.
Swap the ginger
How well each one fits the dish's main ingredients (flour, sugar, molasses, butter, buttermilk):
- Cinnamonfits better
- Jalapenofits better
- Nutmegfits better
- Gingerthe original
Fit is the average pairing score against flour, sugar, molasses, butter, buttermilk. Candidates are from the same food group and used in at least 100 recipes.
