Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
Make the batter
Melt the butter in the milk and let it cool.
In a separate bowl, beat the eggs until light.
Stir the eggs into the cooled milk mixture alternately with the flour.
Dissolve the baking soda in a little water and add it to the batter.
Dissolve the tartaric acid in a little water and add it just before baking.
Cook and serve
Cook the batter on a griddle like buckwheat cakes, buttering them before serving.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Flour
- Forms the structure that holds the cakes together as they cook.
- Eggs
- Add structure and richness, helping the batter set as it cooks.
- Milk
- Provides the liquid that hydrates the flour and gives the batter its moisture.
- Butter
- Adds fat for a softer texture and rich flavour.
- Baking soda
- Reacts with the tartaric acid to release carbon dioxide, which lifts the batter.
- Tartaric acid
- Acid that reacts with the baking soda to make the cakes rise.
The step that matters
Add the tartaric acid just before baking. The acid and baking soda release carbon dioxide gas as soon as they meet. If the batter stands too long, the bubbles escape before cooking sets the structure, so the cakes rise less.
