Why it works: Egg and vanilla are a kitchen classic. They rank in the top 23% of all ingredient pairs, and cooks put them together in 27,347 recipes. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓

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
Preheat your oven to 350°F (175°C).
Separate the egg whites from the yolks.
Make the batter
Beat the egg whites in a large bowl until stiff peaks form.
Beat the egg yolks with a pinch of salt and your chosen flavoring until light and creamy.
Gently fold the egg whites into the yolk mixture until just combined.
Pour the batter into a greased dripping pan.
Bake
Bake for about 25‑30 minutes or until golden and a toothpick comes out clean.

Shared aroma: 1-octen-3-ol (mushroom, earthy).
Egg and vanilla barely smell alike, yet cooks put them together in 27,347 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
- Eggs
- Whipped whites trap air for lift, while yolks add richness and structure to the batter.
- Flavoring
- Adds aroma and taste to the yolk mixture before the whites are folded in.
The step that matters
Gently fold the egg whites into the yolk mixture. Whipped egg whites hold air that gives the cake its rise. Vigorous stirring deflates that foam, so the cake bakes up dense and flat. Folding gently keeps the batter light.
