Why it works: Flour and sugar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Gingerbread Cake
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
Preheat the oven to 350°F (175°C).
Rub the lard into the flour.
Add the candied peel, mixed spice, ginger, and sugar.
Make the batter
Melt the treacle.
Mix the boiling water with the carbonate of soda and then combine it with the melted treacle.
Add this mixture to the dry ingredients along with the beaten egg.
Pour the batter into a well‑greased tin.
Bake
Bake for 1 hour.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Provides the structure that holds the cake together as it bakes.
- Treacle
- Adds sweetness, dark colour, and moisture to the dense crumb.
- Lard
- Rubbed into the flour to add fat, giving a tender texture.
- Egg
- Binds the batter and helps set the crumb as it bakes.
- Carbonate of soda
- Reacts with the acidic treacle and hot water to lift and lighten the cake.
The step that matters
Mixing the carbonate of soda with the boiling water. Carbonate of soda needs to dissolve fully and react with the acidic treacle in the batter; if it is not well dispersed, the cake may rise unevenly or stay heavy in spots.
Swap the ginger
How well each one fits the dish's main ingredients (flour, sugar, egg):
- Jalapenofits better
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
Fit is the average pairing score against flour, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
