Why it works: Butter and flour 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 ↓

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
Preheat the oven to 350°F (175°C).
In a bowl, beat together the water, corn starch, and baking powder.
Add sugar and butter, mixing until smooth.
Make the batter
Fold in the egg whites gently.
Gradually add flour, mixing until just combined.
Pour the batter into a greased loaf pan.
Bake
Bake for 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
- Egg whites
- Trapped air and structure give the cake lift and a light, airy crumb.
- Flour
- Forms the gluten and starch framework that holds the cake's structure as it bakes.
- Butter
- Adds fat that tenderises the crumb and carries flavour.
- Sugar
- Adds sweetness and helps keep the crumb moist and tender.
- Corn starch
- Softens the crumb and makes it more tender than flour alone.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
The step that matters
Fold in the egg whites gently. Egg whites hold air that gives the cake its lift. Overmixing or stirring vigorously knocks that air out, leaving a dense, flat loaf.
“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.
