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 ↓
Flannel Cakes
Ingredients
Directions
Make the batter
Melt the butter in the milk and let it cool.
Beat the eggs until light and stir them into the milk mixture.
Gradually add the sifted flour and mix well.
Dissolve the baking soda in a little water and add it to the batter.
Cook and serve
Just before baking, dissolve the tartaric acid in a little water and add it to the batter.
Cook 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
- Eggs
- Beaten eggs add structure and lift to the batter as they set on the griddle.
- Baking soda
- Reacts with the tartaric acid to release gas, helping the cakes rise and turn light.
- Tartaric acid
- Acid that reacts with the baking soda to produce bubbles for rising and a lighter texture.
- Flour
- Provides the main structure that holds the batter together as the cakes set.
- Milk
- Supplies moisture and liquid that hydrates the flour and gives the batter its body.
The step that matters
Adding the tartaric acid just before baking. Baking soda and tartaric acid react as soon as they meet liquid and begin releasing gas. If the acid is added long before the batter hits the griddle, much of the lift is lost, so the cakes come out flatter and denser.
