Name: Banana Chocolate Chip Muffins
Yield: 30 mini muffins or 12 regular muffins

Why it works: Banana and vanilla are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,430 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓

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

What each ingredient does

All-purpose flour: Provides the main structure that holds the muffin together as it bakes.
Ripe bananas: Add moisture and natural sweetness to the batter.
Egg: Binds the batter and helps set the crumb as it bakes.
Baking soda: Reacts with the acidic buttermilk and bananas to lift the muffins as they bake.
Baking powder: Adds additional lift so the muffins rise and stay light.
Buttermilk: Adds acidity and tenderness, and activates the baking soda for rise.

The step that matters

Mix the batter just until combined. Once flour meets liquid, gluten begins to form. Overmixing develops too much gluten, which makes muffins tough and dense instead of tender.
