Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Potato Biscuits
Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a bowl, combine the flour, mashed potatoes, and salt.
Add butter gradually until the mixture forms a paste.
Shape and bake
Roll out the paste into rounds the size of a large saucer.
Bake in a hot oven at 400°F (200°C) until golden.

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.

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
- All-purpose flour
- Provides the main structure that holds the biscuits together.
- Boiled potatoes
- Adds moisture and a soft, tender crumb to the dough.
- Butter
- Adds fat that tenderizes the dough and promotes browning in the oven.
The step that matters
Bake until golden. A hot oven browns the surface quickly through the Maillard reaction, so the biscuits can darken before the centre is fully cooked. Check them as they near golden.
Swap the potato
How well each one fits the dish's main ingredients (flour, butter):
- Shallotfits better
- Leekfits better
- Arrowrootfits better
- Potatothe original
Fit is the average pairing score against flour, butter. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
