Why it works: Flour and nutmeg are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 18,623 recipes. Both carry isobutyraldehyde, which smells malty, green. 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.
Prepare
Preheat the oven to 350°F (175°C).
Make and bake the batter
In a large bowl, mix the flour, brown sugar, butter, eggs, currants, citron, and grated nutmegs thoroughly.
Dissolve the baking soda in a small amount of water and add it to the mixture just before baking.
Pour the batter into three greased loaf pans.
Bake in the preheated oven until a toothpick inserted in the center comes out clean.

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 structure that holds the dense batter together as it bakes.
- Brown sugar
- Adds sweetness, moisture and a caramel-like flavor and browning.
- Butter
- Adds fat for tenderness and rich flavor in the crumb.
- Eggs
- Bind the batter and help set the structure during baking.
- Baking soda
- Reacts with the batter's acidity to produce gas that helps it rise.
The step that matters
Adding the baking soda. Baking soda needs an acid in the batter to release gas and lift the cake. Dissolving it in water and adding it just before baking keeps that gas from escaping before the cake reaches the oven.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, nutmeg):

Fit is the average pairing score against flour, sugar, butter, egg, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
