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
Make the dough
In a bowl, combine sour milk and baking soda.
Add the beaten egg and mix well.
Gradually add flour until the dough is stiff enough to roll out thinly.
Shape and fry
Roll the dough to a thickness similar to wafers and cut into round shapes.
Fry the rounds in hot oil like doughnuts until golden brown.
Serve hot with syrup.

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
- Its acidity reacts with baking soda to produce gas, helping the dough rise and turn tender.
- Baking soda
- Reacts with the acidic sour milk to release carbon dioxide, leavening the dough.
- Egg
- Binds the dough and adds structure and richness.
- Flour
- Forms the gluten network that gives the dough its structure and stiffness for rolling.
The step that matters
Fry the rounds in hot oil. If the oil is not hot enough, the puffs absorb excess oil and turn greasy and heavy instead of browning quickly. Hot oil seals the surface fast, so the gas from the leavening expands the dough and the rounds puff up.
