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 ↓
French Rolls
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the sponge
Peel the potatoes and boil them in the water.
Press and drain the potatoes through a colander.
When cool enough, add flour to make a thick batter and beat well.
Make this sponge early in the morning.
When light, transfer to a bread pan.
Make the dough
Add salt, lard, and enough flour for a soft dough.
Mix and let rise in a warm place.
When risen, knead down.
Let rise again, repeating this process 5 or 6 times.
Shape and bake
Cut the dough into small pieces.
Mold into rolls about 1 inch thick and 5 inches long.
Roll in melted butter or sweet lard.
Place in well-greased baking pans.
Press the rolls closely together so they are about half an inch wide.
Let rise for a short time.
Bake for 20 minutes at 400°F (200°C).
If the tops brown too quickly, cover with paper.

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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide starch and moisture that help the sponge rise and keep the rolls soft.
- Yeast
- Ferments the sugars in the sponge and dough, producing gas that makes the rolls rise.
- Flour
- Forms the gluten network that gives the dough structure to trap gas and hold its shape.
- Lard
- Adds fat that tenderizes the crumb and gives the rolls a softer texture.
The step that matters
Letting the dough rise fully before shaping. Each rise lets yeast produce gas and gluten stretch. Rising too short leaves dense rolls, while over-rising can collapse the structure, so the dough should look light and airy before the next step.
