Why it works: Flour and caraway match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 1,435 recipes. Both carry isobutyraldehyde, which smells malty, green. 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.
Make the batter
Whisk the eggs (yolks and whites) together for 20 minutes.
Carefully beat in the sugar.
Lightly stir in the flour just before pouring into a buttered tin.
If desired, add a few caraway seeds.
Bake
Bake for 30 to 45 minutes at 350°F (175°C).
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Whisked to trap air, giving the cake its light, risen structure.
- Pounded sugar
- Sweetens the cake and helps stabilise the whisked egg foam.
- Fine flour
- Provides the starch that sets the cake's crumb once baked.
The step that matters
Lightly stir in the flour. Overmixing once flour is added develops gluten and deflates the whisked egg foam, making the cake dense and tough. Fold gently and pour promptly so the air bubbles survive into the oven.
Swap the caraway
The recipe marks caraway as optional. How well each one fits the dish's main ingredients (sugar, egg, flour):
- Jalapenofits better
- Cinnamonfits better
- Nutmegfits better
- Carawaythe original
Fit is the average pairing score against sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
