Why it works: Butter and flour 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 ↓
Ginger Rolls
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
In a bowl, mix molasses, melted butter, hot water, ginger, and baking soda.
Gradually add flour to form a batter.
Drop the batter into greased pans.
Bake
Bake in the preheated oven until golden brown.

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 sweetness, moisture, and a dark color, and its acidity reacts with the baking soda.
- Baking soda
- Reacts with the acidic molasses to release gas, lifting and lightening the batter.
- Melted butter
- Adds fat, which tenderizes the crumb and carries flavor.
- Flour
- Provides structure as its proteins and starch set during baking.
- Ginger
- Provides the warm, spicy aroma that defines the rolls.
The step that matters
Gradually add flour to form a batter. Adding flour a little at a time lets you mix it in evenly and stop once the batter reaches the right consistency. Dumping it in at once can leave lumps of dry flour and make the batter too stiff or too thin.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, butter, flour):
- Cinnamonfits better
- Jalapenofits better
- Nutmegfits better
- Gingerthe original
Fit is the average pairing score against molasses, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
