Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Roman War 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.
Make the dough
In a mixing bowl, combine Roman meal, graham meal, white flour, and salt.
Pour scalded milk (or hot potato or rice water) over the mixture.
Add the dissolved yeast cake and beat thoroughly for a few minutes.
Cover and place in a warm area to rise overnight.
Knead and shape
In the morning, add enough white flour to knead the dough.
Knead thoroughly and set aside to rise, covered, until doubled in size.
Shape into loaves and let rise again until doubled.
Bake
Bake in a preheated oven at 350°F (175°C) for one hour.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Shared aroma: isobutyraldehyde (malty, green).
Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Roman meal
- Provides the main body and coarse texture of the loaf.
- Graham meal
- Adds a nutty flavor and a denser, coarser crumb.
- White flour
- Adds gluten for structure so the loaf holds its shape and rises.
- Yeast cake
- Produces carbon dioxide, which makes the dough rise and become airy.
- Scalded milk
- Moistens the flour and adds softness and browning to the crust.
The step that matters
Overnight rise. The dough needs a warm, covered place to ferment slowly. Too cool and the yeast works too little; too hot and it can overproof and collapse, leaving a dense loaf.
