Why it works: Milk and butter 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 ↓
Rochester Jelly 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.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, beat the eggs and mix in the milk, sugar, and butter.
Add the flour, cream of tartar, and baking soda, mixing well.
Divide the batter in half; to one half, add currants, citron, molasses, cinnamon, cloves, nutmeg, allspice, and a little flour.
Bake and assemble
Pour both batters into greased cake tins and bake until golden.
Once cooled, layer the cakes with jelly or jam in between.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and richness as the cakes set.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Flour
- Forms the main structure of the cake crumb.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda to help the cake rise.
- Baking soda
- Reacts with the acid in the batter to produce gas for rising and light texture.
- Molasses
- Adds moisture, dark color, and a deep sweetness to the spiced half.
The step that matters
Pouring and baking both batters. The two batters must be divided evenly and baked in greased tins so the layers rise and release cleanly. Overbaking dries the crumb, and cooling fully before layering prevents the jelly from melting and the layers from sliding.
Swap the currant

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