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 ↓
Plain 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
Sift the baking soda and flour together.
Stir in the sugar.
Rub in the lard, butter, or drippings with your fingers.
Add the raisins.
Stir in the buttermilk.
Mix and bake
Beat the eggs (yolks and whites together) and add to the mixture.
Bake at 350°F (175°C) for 1.5 hours.

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 structure that holds the cake together as it bakes.
- Lard, butter, or drippings
- Coats flour particles to tenderize the crumb and add richness.
- Sugar
- Adds sweetness and helps the cake brown during baking.
- Buttermilk or sour milk
- Adds moisture and acidity that react with the baking soda.
- Baking soda
- Reacts with the acidic buttermilk to release gas that lifts the cake.
- Eggs
- Bind the batter and add structure and moisture to the crumb.
The step that matters
Adding the baking soda and buttermilk. Baking soda needs an acid, here the buttermilk, to produce the gas that raises the cake. If the soda is not evenly sifted through the flour, pockets of bitter soda or uneven rising can occur, and the batter should go into the oven promptly once mixed so the gas is not lost.
