Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks: Add richness and colour to the gold batter.
Egg whites: Add lift and a light, tender crumb to the silver batter.
Butter: Adds fat for tenderness and a rich flavour.
Flour: Provides the structure that holds the cake together.
Sour milk: Adds acidity that reacts with baking soda and tenderises the crumb.
Baking soda: Reacts with the acidic sour milk to produce gas that helps the cake rise.

The step that matters

Alternate the gold and silver batters. Spooning the two batters in loose alternating layers keeps them distinct. Overmixing or pouring them together blends them into one colour, so the gold and silver effect is lost.
