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 ↓
Republican 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.
Prepare
Preheat the oven to 350°F (175°C).
Prepare and butter the cake tins.
Sift the baking soda into the flour.
Make the batter
Cream the butter and sugar together until light.
Beat the eggs separately, then add them to the butter and sugar mixture gradually.
Mix in the sour cream and dissolved baking soda if using milk.
Gently fold in the flour until just combined.
Dredge the raisins with flour and fold them in last.
Bake
Bake slowly until the cake is evenly heated and cooked through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that sets the cake's crumb as it bakes.
- Butter
- Creaming with sugar traps air, giving the cake a tender, rich texture.
- Sugar
- Sweetens the cake and helps create a light, creamed base with the butter.
- Eggs
- Add structure and richness, and help bind the batter together.
- Sour cream
- Adds moisture and tanginess, and reacts with the baking soda to help the cake rise.
- Baking soda
- Reacts with the acidic sour cream to produce gas, helping the cake rise.
The step that matters
Fold in the flour gently until just combined. Once flour meets liquid, gluten begins to form. Overmixing toughens the cake, so the flour should be folded in only until no dry streaks remain.
Swap the nutmeg
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, cream, coffee, raisin):
- Cinnamonfits about as well
- Nutmegthe original
- Capersfits less well
- Jalapenofits less well
Fit is the average pairing score against flour, sugar, butter, egg, cream, coffee, raisin. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
