Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whole wheat flour
- Provides structure and a denser, slightly nutty crumb.
- Unbleached flour
- Provides structure so the brownies hold together when cut.
- Sugar
- Adds sweetness and helps keep the crumb moist and tender.
- Unsweetened applesauce
- Adds moisture in place of fat, keeping the brownies soft.
- Egg whites
- Provide structure and help set the batter as it bakes.
The step that matters
Bake until just set. Baking past the point where the edges are firm and the center is set dries out the brownies, because moisture keeps evaporating and the starch and proteins continue to firm. Pulling them at that point keeps the center moist and fudgy.
Swap the vanilla
How well each one fits the dish's main ingredients (wheat, flour, sugar, egg):
- Raisinfits better
- Vanillathe original
- Blueberryfits less well
- Figfits less well
Fit is the average pairing score against wheat, flour, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
