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 ↓
Cider 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a mixing bowl, cream together the sugar and butter.
Add the beaten egg and mix well.
Stir in the cider and baking soda.
Gradually add flour until the batter is thick like pound cake.
Fold in raisins if desired.
Bake
Pour the batter into a greased cake pan and bake for about 30-40 minutes or until a toothpick comes out clean.

Butter and flour 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
- Butter
- Adds fat that tenderises the crumb and carries flavour.
- Egg
- Binds the batter and adds structure as it sets in the oven.
- Cider
- Provides liquid and acidity that reacts with the baking soda.
- Baking soda
- Reacts with the acidic cider to produce gas that lifts the cake.
- Flour
- Forms the gluten and starch network that gives the cake its structure.
The step that matters
Stir in the cider and baking soda, then add flour promptly. Baking soda reacts with the acid in the cider as soon as they meet, releasing gas. Delaying the bake or overmixing after that can knock out some of that lift and toughen the crumb, so the batter should go into the pan and oven without long waits.
