Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. 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
Dissolve the baking soda in a small cupful of warm water.
Stir the mixture briskly together.
Pour the mixture into very shallow tins.
Bake
Immediately place the tins in a 350°F (175°C) oven.
Bake for 1.5 hours.

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
- Flour
- Builds the structure that holds the cake's crumb together as it bakes.
- Butter
- Adds fat that tenderises the crumb and carries flavour.
- Sugar
- Sweetens the cake and helps it brown and stay moist.
- Eggs
- Bind the batter and add structure and richness as they set.
- Baking soda
- Releases carbon dioxide once moistened, lifting the batter so it rises.
- Powdered ginger
- Supplies the main spicy aroma and flavour that defines a gingerbread.
The step that matters
Place the tins in the oven immediately. Baking soda starts releasing carbon dioxide as soon as it is moistened and mixed. If the batter waits before baking, much of that gas escapes, so the cake rises less well and may turn out dense.
Swap the ginger
How well each one fits the dish's main ingredients (flour, butter, sugar, egg):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Gingerthe original
Fit is the average pairing score against flour, butter, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
