Why it works: Sugar and molasses 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 ↓
Hot Water Gingerbread
Ingredients
Directions
Make the batter
Cream the butter and lard together, then gradually add the brown sugar.
Beat in the eggs until well combined.
Mix the boiling water with the molasses, then add this mixture alternately with the sifted dry ingredients.
Bake
Pour the batter into a greased pan and bake in a slow oven at 300°F (150°C) for 50 to 60 minutes, or 25 to 30 minutes for individual portions.

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
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Molasses
- Adds moisture, dark color and rich, sweet flavor to the gingerbread.
- Baking soda
- Reacts with the acidic molasses to produce gas that lightens the crumb.
- Brown sugar
- Adds sweetness, moisture and a deep caramel flavor to the cake.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Butter and lard
- Add fat for tenderness and a soft, moist texture.
The step that matters
Adding the boiling water and molasses mixture alternately with the dry ingredients. Boiling water melts the fat and dissolves the sugar and soda evenly, and alternating additions keep the batter smooth. Overmixing once flour is added can develop gluten and toughen the crumb.
Swap the ginger
How well each one fits the dish's main ingredients (butter, sugar, egg, molasses, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against butter, sugar, egg, molasses, flour. Candidates are from the same food group and used in at least 100 recipes.
