Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and moisture to the crumb.
- Flour
- Forms the main structure that holds the cake's shape as it bakes.
- Brown sugar
- Adds sweetness, moisture and a soft, tender texture.
- Grated chocolate
- Adds deep chocolate flavor, color and some richness to the cake.
- Baking soda
- Helps the layers rise by releasing gas in the batter.
The step that matters
Cook the chocolate mixture slowly until thick. Cooking slowly and stirring constantly keeps the mixture from scorching on the bottom and helps any eggs cook smoothly without curdling, giving a thick, even base for the batter.
