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 ↓
Raised Potato-cake
Ingredients
Directions
Make the batter
In a bowl, combine mashed potatoes, flour, butter, salt, and enough milk to create a batter similar to griddle cakes.
Add the fresh yeast and let the mixture rise until light and bubbly.
Bake
Dissolve the baking soda in warm water and stir it into the batter.
Pour the batter into muffin tins and bake until golden.

Flour and butter 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
- Mashed potatoes
- Provide starch and moisture that give the cakes a soft, tender body.
- All-purpose flour
- Forms the main structure of the batter as it sets during baking.
- Fresh yeast
- Produces gas as it ferments, making the batter light and bubbly before baking.
- Baking soda
- Reacts with acidity in the batter to release gas, helping the cakes rise further.
- Butter
- Adds fat for richer flavour and a softer crumb.
The step that matters
Letting the batter rise until light and bubbly. Yeast needs time to ferment and trap gas in the batter. Rising too briefly leaves the cakes dense, while the baking soda added later only supplements this lift rather than replacing it.
Swap the potato
How well each one fits the dish's main ingredients (flour, butter, milk):
- Potatothe original
- Arrowrootfits about as well
- Leekfits less well
- Shallotfits less well
Fit is the average pairing score against flour, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
