Why it works: Molasses and sugar are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
In a cup, pour boiling water over baking soda to dissolve.
In a large bowl, mix molasses, brown sugar, butter, eggs, salt, and ginger.
Add the dissolved baking soda and stir well.
Gradually add flour, mixing until smooth.
Pour the batter into a greased baking pan.
Bake
Bake at 350°F (175°C) until a toothpick comes out clean.

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
- Molasses
- Adds dark color, moisture, and a deep, sticky sweetness to the batter.
- Brown sugar
- Adds sweetness and moisture, and helps the crumb stay soft and tender.
- Baking soda
- Reacts with the acidic molasses to produce gas that lifts the batter and helps it brown.
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Flour
- Provides the starch and gluten network that gives the cake its structure.
- Butter
- Adds fat for richness and a tender texture.
The step that matters
Dissolve the baking soda fully before adding it. Baking soda needs moisture and mixing to disperse evenly. Undissolved clumps can leave soapy or bitter pockets and uneven rising, so stir the dissolved mixture well before adding it to the batter.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, butter, egg, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against molasses, sugar, butter, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
