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
Make the dough
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.
Stir in Sultana raisins and enough flour to form a stiff batter.
Let rise again, then work down and spread in buttered pans to about ½ inch thick.
Top and bake
When light, brush the top with melted butter, then sprinkle with sugar and chopped nuts.
Optionally, cover with a paste made of 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
What each ingredient does
- Flour
- Forms the gluten network that gives the cake its structure and holds the stiff batter.
- Yeast
- Ferments the dough so it rises and becomes light and airy.
- Eggs
- Add richness and help bind the batter for a tender crumb.
- Butter
- Adds fat for a softer, richer crumb and flavor.
- Sugar
- Sweetens the cake and helps the top brown lightly.
- Sultana raisins
- Add sweetness and moist pockets of fruit throughout the cake.
The step that matters
Let the dough rise until nearly double before adding the rest. Yeast needs time to build gas and structure in the first rise. Adding the other ingredients too early or skipping the rise leaves the cake dense, because the dough never gets the lift it needs.
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.
