Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 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 large bowl, cream together the butter and sugar.
Add the eggs one at a time, mixing well after each addition.
Dissolve the pearlash in the cider and add it to the mixture.
Gradually stir in the flour until well combined.
Bake
Pour the batter into a greased baking pan.
Bake for about 30-40 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and add richness and tenderness to the crumb.
- Sugar
- Sweetens the cake and helps the butter hold air when creamed.
- Eggs
- Add structure and binding, and help the batter set as it bakes.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Cider
- Adds moisture and acidity to the batter, and dissolves the pearlash.
- Pearlash
- Reacts with the acidic cider to release gas, helping the cake rise.
The step that matters
Dissolve the pearlash in the cider. Pearlash is a leavening agent that reacts with acid in the cider to release carbon dioxide. It should be fully dissolved before mixing so the gas forms evenly and the cake rises uniformly rather than developing dense or uneven spots.
“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.
