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 Coffee Cake
Ingredients
Directions
Dissolve the yeast in lukewarm water.
Add flour and beat well; let rise until nearly double in size.
Mix in creamed butter, sugar, and beaten eggs.
Fold in Sultana raisins and enough flour to form a stiff batter.
Let the dough rise, then work it down and spread it in buttered pans to about ½ inch thick.
Once light, brush the top with melted butter, then sprinkle with sugar and chopped nuts.
Optionally, coat with a paste made from confectioners' sugar and water.
For sweet rusks, roll out the dough, cut into shapes, and add more sugar, raisins, and nuts.

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
Swap the nuts
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, raisin):
- Almondfits better
- Chestnutfits better
- Pistachiofits better
- Nutsthe original
Fit is the average pairing score against flour, butter, sugar, egg, raisin. Candidates are from the same food group and used in at least 100 recipes.
