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 ↓
Lemon 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.
Make the cake
Preheat the oven to 350°F (175°C).
Cream together the butter and sugar until light and fluffy.
Add the flour, sweet milk, and baking powder, mixing well.
In a separate bowl, whip the egg whites until stiff peaks form.
Fold the whipped egg whites into the batter gently.
Pour the batter into a greased cake pan and bake for 25-30 minutes.
Make the filling
For the filling, dissolve the corn starch or flour in a little water.
In a saucepan, combine the dissolved mixture with lemon juice, lemon zest, egg yolks, sugar, butter, and boiling water.
Cook in a double boiler until thickened, then remove from heat and fold in the whipped egg whites.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Builds the cake's structure as its proteins set during baking.
- Eggs
- Whipped whites lighten the batter, while yolks enrich the filling and help it thicken.
- Butter
- Adds richness and a tender crumb to the cake and a smooth body to the filling.
- Baking powder
- Releases gas in the batter so the cake rises in the oven.
- Corn starch
- Thickens the filling as it heats, giving it a spoonable set.
- Lemons
- Juice adds sharp acidity and zest adds bright aroma to the filling.
The step that matters
Cooking the filling until thickened. Corn starch thickens only when it heats fully, but the egg yolks can scramble and curdle if the mixture overheats. Gentle double-boiler heat, stirred steadily, keeps the filling smooth.

Fit is the average pairing score against butter, sugar, flour, milk, egg, corn. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
