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
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 350°F (175°C).
Rub the cream of tartar into the flour in a large bowl.
Dissolve the baking soda in the warm water and add it to the flour mixture.
Stir in a little salt and gradually add sweet milk until a dough forms.
Bake
Shape the dough into loaves and place them in the oven.
Bake for about 45 minutes until the loaves are light brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: acetaldehyde (pungent, ethereal).
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
- All-purpose flour
- Provides the structure that holds the loaves together as they bake.
- Cream of tartar
- Reacts with the baking soda to produce carbon dioxide, helping the bread rise.
- Baking soda
- Reacts with the acid in cream of tartar to release gas, leavening the dough.
- Sweet milk
- Adds moisture and richness, bringing the flour into a workable dough.
The step that matters
Dissolving the baking soda in the warm water. Baking soda must be fully dissolved and evenly mixed into the flour so the leavening reaction is spread throughout the dough. Clumps can leave bitter, yellow pockets and uneven rising.
“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.
