Why it works: Raisin and flour 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
The book says “a good oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar together.
Beat in the egg.
Add the raisins and spices.
Warm the coffee slightly and dissolve the baking soda in it, then add to the mixture.
Stir in the flour and cream of tartar.
Bake
Bake in a good oven at 350°F (175°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air and give the cake a tender, rich crumb.
- Sugar
- Sweetens the cake and helps the creamed butter hold air for a light texture.
- Egg
- Binds the batter and adds structure and moisture as the cake sets.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Cream of tartar
- Acidifies the batter so the baking soda reacts and helps the cake rise.
- Baking soda
- Reacts with the acid in the batter to produce gas that lifts the cake.
The step that matters
Dissolving the baking soda in the coffee. Baking soda must be fully dissolved and mixed through the batter so it reacts evenly with the acid. Undissolved pockets can leave bitter spots or uneven rising.
Swap the cinnamon
How well each one fits the dish's main ingredients (egg, sugar, butter, raisin, flour, cream, coffee):
- Cinnamonthe original
- Nutmegfits about as well
- Capersfits less well
- Jalapenofits less well
Fit is the average pairing score against egg, sugar, butter, raisin, flour, cream, coffee. Candidates are from the same food group and used in at least 100 recipes.
