Flour and egg barely smell alike, yet cooks put them together in 106,462 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

Barley flour
Provides the main structure of the loaf, though it sets less firmly than wheat flour.
Ground rolled oats
Adds body and moisture-holding starch, giving the loaf a softer, denser crumb.
Baking powder
Releases gas in the batter so the loaf rises and becomes lighter in texture.
Eggs
Bind the batter and add structure, moisture and richness to the crumb.
Syrup
Adds sweetness and moisture, and helps the crust brown during baking.

The step that matters

Pour the batter into a loaf pan and bake for one hour or until thoroughly baked. Grain-based batters without wheat gluten set slowly and can look done outside while the centre is still wet. Baking until the centre is fully set prevents a gummy, sunken loaf.
