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 Cake
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.
Make the batter
Beat together the sugar and butter until creamy.
Mix the grape jelly, molasses, and milk in a separate bowl.
Stir the wet mixture into the butter and sugar mixture.
Sift the flour and baking powder together, then add to the mixture.
Add the lemon juice and mace, and mix well.
Beat the egg whites until frothy and fold them into the batter.
Bake
Just before baking, stir in the raisins, currants, and citron or almonds.
Pour the batter into a prepared pan and bake at 350°F (175°C) for 1.5 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and give the cake a tender, rich crumb.
- Egg whites
- Whipped and folded in to add lift and a light, airy structure.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- White sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- New orleans molasses
- Adds moisture, deep flavor, and dark color through its sugars.
The step that matters
Folding in the beaten egg whites. Whites beaten until frothy hold air that gives lift. Stirring them in roughly or overmixing knocks that air out, so the cake bakes up dense instead of light.
Swap the mace
How well each one fits the dish's main ingredients (sugar, butter, grape, molasses, milk, flour, lemon):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits better
- Macethe original
Fit is the average pairing score against sugar, butter, grape, molasses, milk, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
