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

What each ingredient does

Flour: Provides the starch and gluten network that gives the brownies their structure.
Egg whites: Add structure and help bind the batter, setting as it bakes.
Butter: Adds fat for richness and a tender, moist crumb.
Cocoa: Supplies the chocolate flavour and deep brown colour.
Barbados sugar: Adds sweetness and moisture, and helps keep the brownies soft.
Baking soda: Reacts to lift the batter slightly and aid browning.

The step that matters

Add pecans and flour and mix 3-4 minutes at low speed. Once flour is added, its proteins begin forming gluten, and extra mixing makes the brownies tougher and more cake-like. Keeping the speed low and the time within the stated range helps preserve a fudgy texture.
