Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
German Tea 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.
Make the sponge
Combine yeast, water, and a portion of the flour to create a sponge.
Let the sponge stand for three hours.
Make the dough
Add the remaining flour, sugar, raisins, lemon zest, lemon juice, melted butter, and beaten egg whites to the sponge. Mix until a dough forms.
Place the dough in a Turkshead mold.
Let the dough stand for one hour.
Bake
Preheat the oven to 350°F (175°C).
Bake until golden.

Flour and butter 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
- Forms the gluten network that gives the cake its structure.
- Eggs
- Add structure and richness, with whipped whites helping the crumb rise and set.
- Yeast
- Ferments the sponge, producing gas that makes the dough rise.
- Butter
- Adds fat for tenderness and a richer crumb.
- Raisins
- Add sweetness and chewy moisture throughout the cake.
The step that matters
Letting the sponge stand for three hours. The yeast needs time to ferment the flour and water. Under-fermenting leaves the dough dense and slow to rise, while the gas produced by fermentation gives the cake its lift.

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