Why it works: Flour and sugar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Hot Rolls
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Boil the Irish potato until fully cooked, then let it cool in the water.
Mix the cooled potato with the yeast until well combined.
In a large bowl, combine the flour, lard, salt, and sugar, mixing thoroughly.
Work the mixture well, then cover and let it rise overnight.
Shape and bake
The next morning, shape the dough into rolls and place them in a deep pan.
Allow the rolls to rise until they reach the top of the pan.
Bake in a moderate oven at 350°F (175°C) until thoroughly cooked.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the gluten network that gives the rolls their structure.
- Yeast
- Produces carbon dioxide gas during fermentation, which makes the dough rise.
- Irish potato
- Adds moisture and starch that help keep the rolls soft.
- Lard
- Adds fat that tenderizes the crumb and softens the texture.
- Sugar
- Feeds the yeast and adds a little sweetness and browning.
The step that matters
Overnight rise. The dough must rise slowly and fully before shaping. Yeast needs time to build gas and flavor, and a dough that is under-proofed or over-proofed will bake up dense or collapsed.
Swap the potato
How well each one fits the dish's main ingredients (flour, sugar):
- Arrowrootfits better
- Beetrootfits better
- Sweet potatofits better
- Potatothe original
Fit is the average pairing score against flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
