Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Fruit Loaf Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat your oven to 350°F (175°C).
In a large bowl, mix the flour with the cream of tartar.
Make a well in the center and add the softened butter, brown sugar, molasses, sweet milk, and eggs.
Mix everything together with your hands until well combined.
Flour the raisins and currants, then fold them into the batter along with the grated nutmeg and cinnamon.
Bake
Pour the batter into two loaf pans.
Bake for 2 hours or 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
- Forms the structure that holds the fruit and crumb together.
- Cream of tartar
- Acidifies the batter so it reacts with the baking soda to help it rise.
- Baking soda
- Reacts with the acidic cream of tartar to produce gas that lifts the batter.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- New orleans molasses
- Adds moisture, deep sweetness, and browning to the crumb.
- Butter
- Adds fat for tenderness and flavor in the crumb.
The step that matters
Flouring the raisins and currants. Dusting the dried fruit with flour helps it stay suspended in the batter rather than sinking to the bottom of the loaf during baking.
Swap the cinnamon
How well each one fits the dish's main ingredients (butter, sugar, molasses, milk, egg, flour, cream):
- Cinnamonthe original
- Nutmegfits about as well
- Gingerfits less well
- Allspicefits less well
Fit is the average pairing score against butter, sugar, molasses, milk, egg, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
