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
Preheat the oven to 350°F (175°C).
Make the dough
Rub the cream of tartar into the flour and add a little salt.
Dissolve the baking soda in warm water and stir it into the flour mixture.
Gradually add sweet milk until a dough forms.
Shape and bake
Mould the dough into loaves and place them on a baking sheet.
Bake for about 45 minutes until 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
- Forms the structure of the dough once it is mixed with liquid.
- Cream of tartar
- Reacts with the baking soda to produce acid and gas, helping the bread rise.
- Baking soda
- Reacts with the acid in cream of tartar to release carbon dioxide, lifting the loaves.
- Sweet milk
- Adds moisture and richness, helping bind the dough and brown the crust.
The step that matters
Dissolve the baking soda in warm water and stir it into the flour mixture. Baking soda must be fully dissolved and evenly distributed so that it reacts with the cream of tartar throughout the dough. Unevenly mixed leavening produces dense patches 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.
