Why it works: Wheat and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,373 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Oat-flour and Wheat Bread

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare the dough

In a large bowl, combine the wheat flour and oat flour.
Dissolve the yeast in the liquid (if using dry yeast, activate it first).
Add the yeast mixture to the flour mixture.
Stir in the molasses or syrup, fat, and salt.
Mix until a dough forms, then knead until smooth.
Cover and let rise overnight.

Shape and bake

Shape the dough into loaves and place in greased pans.
Let rise again until doubled in size, then bake at 350°F (175°C) for 30-40 minutes.

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

What each ingredient does

Oat flour: Gives the loaf its nutty, hearty flavour and a denser crumb than wheat flour alone.
Wheat flour: Supplies gluten, which builds the structure that traps gas and lets the loaf rise.
Yeast: Produces carbon dioxide during the long rise, leavening the dough and giving it airy texture.
Molasses or syrup: Feeds the yeast and adds sweetness, moisture and browning to the crust.
Fat: Tenderises the crumb and adds moisture, softening the texture of the bread.

The step that matters

Knead until smooth. Kneading develops gluten, which forms the elastic network that holds gas during rising. Oat flour has little gluten, so the wheat flour must carry the structure; under-kneading leaves a crumbly, dense loaf.
