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 ↓
Raised Potato Rolls
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a bowl, mix the mashed potatoes, nut cream, yeast, and salt.
Gradually add flour until the mixture forms a moderately stiff batter.
Cover the bowl and place it in a warm area to rise until light.
Once risen, add more flour to make the dough stiff enough to knead without sticking.
Knead the dough for 10 to 15 minutes.
Shape the rolls
Roll the dough out to about ½ inch thick.
Cut the dough with a biscuit cutter.
Place two pieces together in an oiled baking pan.
Let the rolls rise until they double in size.
Brush the tops with peanut oil.
Bake
Bake in a 350°F (175°C) oven for about 20 minutes.
You can substitute sweet potatoes for Irish potatoes if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Add moisture and starch that give the rolls a soft, tender crumb.
- Nut cream
- Adds richness and fat, softening the crumb and adding flavor.
- Yeast
- Produces gas as it ferments, causing the dough to rise and become light.
- Flour
- Provides gluten and structure that hold the risen dough together.
- Peanut oil
- Adds fat to the brushed tops, helping them brown and stay soft.
The step that matters
Adding flour after the first rise. Adding too much flour before the dough has risen makes it dense, while adding too little leaves it too sticky to knead. Kneading only once the dough is stiff enough develops gluten for a light, well-structured roll.
Swap the potato
How well each one fits the dish's main ingredients (cream, flour, peanut oil):
- Welsh onionfits better
- Spinachfits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against cream, flour, peanut oil. Candidates are from the same food group and used in at least 100 recipes.
