Why it works: Potato and milk are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 3,611 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. The science ↓
Potato Biscuit
Ingredients
Directions
Make the dough
Add milk and salt to the mashed potatoes.
Work in flour until the dough is consistent enough to roll out.
Shape and bake
Cut the dough into biscuit shapes.
Bake on a griddle or floured pan.
Alternatively, add yeast, let the dough rise until light, then shape into biscuits or rolls and bake in the oven.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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 the bulk and moisture that make the dough soft and tender.
- Flour
- Gives the dough enough structure to hold its shape when rolled and cut.
- Milk
- Adds moisture and softness, helping the dough come together.
- Yeast
- Produces gas as it ferments, so the dough rises and becomes light.
The step that matters
Work in flour until the dough is consistent enough to roll out. Mixing flour into the dough develops gluten. Overworking it makes the biscuits tough and dense, so stop once the dough holds together.
Swap the potato
How well each one fits the dish's main ingredients (milk, flour):
- Arrowrootfits better
- Potatothe original
- Sweet potatofits about as well
- Parsnipfits about as well
Fit is the average pairing score against milk, flour. Candidates are from the same food group and used in at least 100 recipes.
