Why it works: Milk and flour 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 ↓

Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Dissolve the baking soda in the sour milk.
Make and bake the batter
Stir in the sugar, salt, graham flour, and all-purpose flour until well combined.
Pour the batter into a greased loaf pan.
Bake for about 1 hour or until a toothpick inserted in the center comes out clean.

Milk and flour 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
- Baking soda
- Reacts with the acidic sour milk to release carbon dioxide, lifting the batter as it bakes.
- Sour milk
- Provides liquid and acidity that activates the baking soda and tenderizes the crumb.
- Graham flour
- Supplies the bulk of the structure and the coarse, nutty texture of the bread.
- All-purpose flour
- Adds gluten-forming protein that gives the loaf structure and a softer crumb.
- Sugar
- Adds sweetness and helps the crust brown during baking.
The step that matters
Dissolve the baking soda in the sour milk. Baking soda needs an acid to work, and the sour milk supplies it. The soda must be fully dissolved and mixed in promptly, so the carbon dioxide is evenly distributed and the loaf rises rather than forming uneven pockets or a flat, dense texture.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
