Why it works: Ginger and cinnamon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,380 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Soft Ginger 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.
Make the batter
Cream together the butter and brown sugar.
Add the molasses, milk, ginger, and cinnamon; mix well.
Beat in the egg yolks, then fold in the beaten egg whites.
Gradually add the sifted flour, mixing thoroughly.
Dissolve the baking soda in water and add to the mixture.
Bake
Pour the batter into two greased and lined square bread pans.
Bake in a moderate oven at 350°F (175°C) for 40 to 60 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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
- Eggs
- Egg whites add lift and a lighter crumb, while yolks enrich the batter.
- Baking soda
- Reacts with the acidic molasses and sour milk to produce gas that makes the cake rise.
- Molasses
- Adds moisture, dark colour, and the deep sweetness that defines the cake.
- All-purpose flour
- Provides the structure that sets the batter as the cake bakes.
- Butter
- Adds fat for a tender texture and rich flavour.
The step that matters
Dissolve the baking soda in water and add to the mixture. Baking soda must be fully dissolved and mixed in promptly so it reacts with the acidic molasses and milk evenly. Uneven mixing leaves pockets of bitter soda and an uneven rise.
Swap the ginger
How well each one fits the dish's main ingredients (butter, sugar, molasses, milk, cinnamon, egg, flour):
- Nutmegfits better
- Cardamomfits better
- Clovefits about as well
- Gingerthe original
Fit is the average pairing score against butter, sugar, molasses, milk, cinnamon, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
