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 ↓
Cochineal Marble 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.
Prepare the batter
Preheat your oven to 350°F (175°C).
Cream the butter and powdered sugar together until smooth.
Beat the egg whites until frothy.
Gradually combine the egg whites with the butter and sugar mixture.
Marble and pour
Soak the cochineal in hot water, bruise it, and strain it into three-fourths of a teacup of the cake batter.
Pour the batter into the cake tin, marbling with the red dough as you go.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and tenderness, as its fat coats the flour and limits toughness.
- Powdered sugar
- Sweetens the cake and, creamed with butter, helps trap air for a lighter crumb.
- Flour
- Provides the structure that sets as the cake bakes.
- Egg whites
- Whipped into foam, they add lift and help set the crumb.
- Baking powder
- Releases gas when heated, helping the cake rise.
- Cochineal
- Natural red colouring that gives the marbled swirls their colour.
The step that matters
Gradually combining the egg whites. Whipped egg white foam traps air that makes the cake light. Adding it gradually and folding gently keeps that foam from collapsing, while overmixing deflates it and yields a denser cake.
