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

What each ingredient does

Eggs
Whites trap air for lift, while yolks add richness and structure to the crumb.
Flour
Provides the structure that holds the sponge together as it sets in the oven.
Molasses
Adds moisture, dark colour and a deep sweetness to the cake.
Butter
Adds fat for tenderness and a rich, soft texture.
Sour milk with soda
Acid reacts with soda to produce gas that helps the cake rise.
Sugar
Sweetens the batter and helps the yolks whip to a thick, light texture.

The step that matters

Mix all together, but avoid beating.. Once flour is in, overbeating develops gluten and toughens the cake. Gentle folding keeps the air from the whites and the crumb tender.
