Name: Gluten-free Banana Bread
Ingredients: 1 cup brown rice flour; 1 cup white rice flour; 1/4 cup each potato starch flour and tapioca flour; 1 teaspoon xanthan gum; 1 tablespoon gf baking powder; 1/2 teaspoon salt; 1 tablespoon egg replacer (dry ingredients mixed); 1/2 cup butter (or canola oil); 2/3 cups honey or brown sugar -or- 1/2 cup fructose cream oil and sugar; 1-1/2 cups thoroughly mashed overripe bananas

Why it works: Rice and potato match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 851 recipes. Both carry 2-acetyl-1-pyrroline, which smells popcorn, roasted. The science ↓

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Brown rice flour: Provides the main structure and bulk in place of wheat flour.
Xanthan gum: Binds the gluten-free flours so the loaf holds together instead of crumbling.
Baking powder: Releases gas in the batter so the loaf rises and becomes lighter.
Overripe bananas: Add moisture, sweetness and flavor while helping keep the crumb tender.
Butter or canola oil: Adds fat that keeps the bread moist and tender.
Honey or brown sugar: Adds sweetness and helps the crust brown during baking.

The step that matters

Stir the batter only until moist. Gluten-free flours have no gluten network to toughen, but overmixing can still break down the starch structure and make the loaf dense. Mixing just until combined keeps the texture light.
