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 ↓
Coffee Cake
Ingredients
Directions
Make the dough
Mix the potatoes, yeast, lukewarm milk, and sugar together, then add the well-beaten eggs.
Warm the flour in a pan, make a nest in the center, and pour the liquid mixture into this nest.
Mix until about ⅔ of the flour is incorporated, then add the melted shortening and salt.
Continue mixing the dough until it is soft and smooth.
If using Sultana raisins, add them when the shortening and salt are incorporated. If using dark raisins, add them when molding the cakes.
Rise and shape
Place the dough in a greased bowl, cover it, and set aside to rise until doubled in bulk.
Press the dough back down and allow it to rise again before shaping into cakes.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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
- Potatoes
- Add moisture and a tender crumb to the dough.
- Yeast
- Produces gas that makes the dough rise.
- Eggs
- Add richness and structure to the dough.
- Flour
- Forms the gluten network that gives the dough its structure.
- Shortening
- Adds fat that softens the crumb and tenderizes the dough.
- Sugar
- Feeds the yeast and adds sweetness and browning.
The step that matters
Mixing the dough until soft and smooth. Thorough kneading develops gluten so the dough traps gas during rising. Under-mixing leaves a weak, dense structure, while adding fat before the gluten forms can coat the flour and limit its development.
Swap the potato
How well each one fits the dish's main ingredients (milk, sugar, egg, flour, raisin):
- Arrowrootfits better
- Sweet potatofits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against milk, sugar, egg, flour, raisin. Candidates are from the same food group and used in at least 100 recipes.
