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 ↓
Soft Molasses Cake
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a bowl, mix together the molasses and hot water.
In another bowl, cream the butter and add the molasses mixture.
Incorporate the flour, baking soda, egg, and ginger into the mixture.
Pour the batter into a greased cake pan.
Bake
Bake for 30-35 minutes or until a toothpick comes out clean.

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
- Molasses
- Provides sweetness, dark colour and moisture, and a deep flavour to the cake.
- All-purpose flour
- Forms the structure that holds the cake together as it sets.
- Baking soda
- Reacts with the acidic molasses to produce gas that makes the cake rise.
- Egg
- Adds structure and binds the batter as it sets in the oven.
- Butter
- Adds fat for tenderness and richness in the crumb.
The step that matters
Adding the baking soda. Baking soda needs an acid, which molasses supplies, to release gas and lift the cake. Mixing it in evenly keeps the rise even and prevents dense pockets or a soapy taste from unreacted soda.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, flour, butter, egg):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Gingerthe original
Fit is the average pairing score against molasses, flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
