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 ↓

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
- Sour milk
- Provides the liquid and acidity that react with baking soda to lift the batter.
- Flour
- Forms the structure of the cakes once the batter is set by heat.
- Baking soda
- Reacts with the sour milk's acidity to produce gas that makes the cakes rise.
- Molasses
- Adds sweetness, depth of flavour and a darker colour to the cakes.
The step that matters
Add the dissolved baking soda and stir well. Baking soda starts reacting with the acid in the sour milk as soon as it meets liquid. Stirring it in evenly distributes the gas-producing reaction through the batter, and baking right away keeps the bubbles from escaping before the heat sets the structure.
