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 ↓
Cold Water 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 sugar and butter.
Add the cold water and mix well.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the sugar and butter mixture.
Sift together the flour and baking powder, then gradually add to the mixture.
Pour the batter into a greased cake pan.
Bake
Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the cake's main structure once it sets in the oven.
- Sugar
- Adds sweetness and helps the crumb stay tender and browned.
- Butter
- Adds fat, richness and a tender texture to the crumb.
- Egg whites
- Trap air when beaten, giving the cake lightness and lift.
- Baking powder
- Releases gas in the batter, causing the cake to rise.
- Cold water
- Adds moisture to the batter, keeping the cake from drying out.
The step that matters
Folding in the egg whites. Beaten egg whites hold air that gives the cake its lift. Folding gently keeps that air in the batter, while vigorous stirring would deflate it and produce a denser cake.
“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.
