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 ↓
Grand Duke 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batters
Preheat the oven to 350°F (175°C).
Beat the egg whites until stiff peaks form.
Cream together sugar and butter.
Add sweet milk, corn starch, flour, and baking powder. Mix well.
Fold in the beaten egg whites.
Add lemon flavoring.
Mix egg yolks, brown sugar, butter, sweet milk, molasses, flour, baking powder, spices, raisins, currants, pecans, and vanilla flavoring.
Bake and assemble
Grease two cake pans.
Pour the white batter into one pan and the dark batter into the other.
Bake for 25-30 minutes or until a toothpick comes out clean.
Cool the cakes and layer them with icing in between.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten to stiff peaks, they lighten the batter and give the white layer its airy structure.
- Egg yolks
- Add richness and moisture to the dark batter and help it set.
- Butter
- Adds fat for tenderness and flavor in both batters.
- Flour
- Provides the main structure that sets the cake crumb.
- Baking powder
- Releases gas in the batter so the cakes rise.
- Molasses
- Adds moisture, dark color and a deep sweet flavor to the dark batter.
The step that matters
Folding in the beaten egg whites. Egg whites hold air only while they are stiff. Folding gently keeps that air in the batter, so the white cake rises light instead of dense.
