Why it works: Milk and bread are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 11,466 recipes. Both carry 2-undecenal, which smells sweet. The science ↓
Sour Milk Hot Cakes
Ingredients
Directions
Prepare the batter
Combine sour milk and bread in a bowl and let it sit overnight.
In the morning, dissolve the baking soda in a little hot water and stir it into the sour milk and bread mixture.
Add enough flour to create a thin batter.
Cook
Drop tablespoons of the batter onto a hot griddle and cook until golden brown.

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 the baking soda to produce carbon dioxide, lightening the pancakes.
- Baking soda
- Reacts with the acid in the sour milk to release gas, helping the pancakes rise.
- Flour
- Provides the structure that sets as the pancakes cook.
- Bread
- Soaks up liquid and softens overnight, adding body to the batter.
The step that matters
Dissolving the baking soda and stirring it in. Baking soda must be fully dissolved so it reacts evenly with the sour milk. Clumps leave pockets of bitter residue and uneven rising.
