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

What each ingredient does

Flour: Forms the structure that sets the cake's crumb as it bakes.
Eggs: Bind the batter and add structure and richness as they set.
Buttermilk: Adds moisture and acidity that tenderises the crumb and reacts with the leavener.
Baking soda: Reacts with the acidic buttermilk to produce gas that makes the cake rise.
Cocoa: Gives the cake its chocolate flavour and dark colour.
Sugar: Sweetens the cake and helps it brown and stay moist.

The step that matters

Cool 15 minutes and then remove from pan. Removing the cake too early can make it break, while leaving it too long lets it stick as the sugars cool and harden. Timing the release keeps the crumb intact.
