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 ↓
Potato Biscuit
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the potatoes
Boil the potatoes with their skins on until tender.
Drain and squeeze them with a towel to remove excess moisture.
Remove the skins and mash the potatoes until smooth.
Make the dough
Add the butter, egg, and sweet milk to the mashed potatoes.
Let the mixture cool, then beat in the yeast.
Gradually add flour until a stiff dough forms.
Allow the dough to rise until doubled in size.
Shape and bake
Shape into small cakes and let them rise again.
Bake in a preheated oven at 400°F (200°C) until golden brown.

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
- Potatoes
- Provide the starchy bulk that gives the biscuits a soft, tender crumb.
- Butter
- Adds fat for richness and a tender texture.
- Egg
- Binds the dough and adds structure as it sets in the oven.
- Sweet milk
- Adds moisture and helps the dough come together.
- Yeast
- Produces gas during rising, making the dough light and airy.
- Flour
- Builds the structure of the dough so it holds its shape.
The step that matters
Let the dough rise until doubled in size. Yeast needs time and warmth to produce gas. Rising too briefly leaves the biscuits dense, while the second rise lets the shaped cakes expand before baking.

- Asparagusfits about as well
Fit is the average pairing score against butter, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
