Why it works: Potato and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 5,355 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Potato Biscuits
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
Combine melted shortening, yeast, lukewarm water, mashed potato, beaten egg, and salt in a large bowl. Mix thoroughly.
Gradually add flour, mixing until a dough forms.
Knead the dough until elastic, then cover and let it rise until nearly doubled in size.
Shape and bake
Shape the dough into biscuits and let them rise again.
Bake in a preheated oven at 350°F (175°C) for 25 minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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.

Shared aroma: (e)-2-octenal (fatty, green).
Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Forms the gluten network that gives the dough structure and chew.
- Yeast
- Produces gas that makes the dough rise and become light.
- Mashed potato
- Adds moisture and softness, helping the biscuits stay tender.
- Melted shortening
- Adds fat that tenderizes the crumb and carries flavor.
- Beaten egg
- Adds moisture and richness and helps bind the dough.
The step that matters
Knead the dough until elastic. Kneading develops gluten so the dough can trap the gas produced by yeast. Under-kneaded dough rises poorly and bakes up dense.
Swap the potato
How well each one fits the dish's main ingredients (egg, flour):
- Arrowrootfits better
- Chivefits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against egg, flour. 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.
