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 ↓

Ingredients
Directions
Prepare the dough
Reduce the tartaric acid and salt to a fine powder and mix with the flour.
Dissolve the soda in the milk and pour it several times between two bowls before adding it to the flour.
Quickly work the mixture into a light dough.
Bake
Divide the dough into 2 loaves and place them in a well-heated oven immediately.
Bake for 1 hour.

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
- Flour
- Provides the structure that holds the bread together as it bakes.
- Tartaric acid
- Reacts with the soda to release carbon dioxide, which lifts the dough.
- Carbonate of soda
- Produces carbon dioxide when combined with acid, causing the bread to rise.
- Milk
- Adds moisture that hydrates the flour and dissolves the soda.
The step that matters
Work the dough quickly and bake immediately. Tartaric acid and soda react as soon as they are moistened, releasing carbon dioxide that makes the bread rise. Overworking the dough develops gluten and toughens it, so the mixing should be brief and the loaves should go into the oven without delay.
