Why it works: Flour and caraway match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 1,435 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Melt the butter and treacle together.
Make the batter
In a large bowl, mix the flour, ginger, caraway seeds, sweet pepper, sugar, and baking soda.
Add the melted butter and treacle to the dry ingredients.
Gradually mix in boiling water until the batter reaches a smooth consistency.
Pour the batter into a greased baking pan.
Bake
Bake for 2½ hours or until a toothpick inserted in the center 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
- All-purpose flour
- Provides the main structure that holds the cake together as it sets.
- Treacle (molasses)
- Adds moisture, deep sweetness and a dark color to the cake.
- Unsalted butter
- Adds fat for a tender crumb and richer flavor.
- Baking soda
- Reacts with the acidic treacle to lift the batter as it bakes.
- Granulated sugar
- Adds sweetness and helps the cake brown during baking.
- Powdered ginger
- Contributes warm, spicy aroma that defines the flavor of the cake.
The step that matters
Gradually mix in boiling water. Adding the water slowly lets the batter reach an even, smooth consistency without lumps. Pouring it in all at once can leave dry pockets of flour or make the batter too thin to hold its rise.
Swap the caraway
How well each one fits the dish's main ingredients (flour, butter, ginger, pepper, molasses, sugar):
- Cinnamonfits better
- Cardamomfits better
- Clovefits better
- Carawaythe original
Fit is the average pairing score against flour, butter, ginger, pepper, molasses, sugar. Candidates are from the same food group and used in at least 100 recipes.
