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 ↓

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.
Prepare the sponge
Peel the potatoes and boil them in the water.
Press and drain the potatoes through a colander.
Add flour to the boiled potatoes to make a thick batter.
Beat the batter well.
Add the yeast to the batter to make a sponge.
Let the sponge rise in a warm place until light.
Make the dough
Transfer the sponge to a bread pan.
Add salt, lard, and enough flour to the pan to make a soft dough.
Mix the dough and let rise in a warm place.
Repeat kneading and rising process 5 or 6 times.
Shape and bake
Cut the dough into small pieces.
Shape each piece into a roll about 1 inch thick and 5 inches long.
Roll each roll in melted butter or sweet lard.
Place the rolls in well-greased baking pans.
Press the rolls closely together so they are about half an inch wide.
Let the rolls rise for a short time.
Bake the rolls for 20 minutes at 400°F (200°C).
If the tops brown too quickly, cover with paper.
For larger rolls, cut deeply across each one before baking to create a cleft roll.

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.

What each ingredient does
- Potatoes
- Add starch and moisture that help the dough stay soft and hold gas during rising.
- Yeast
- Ferments the sugars in the sponge, producing gas that makes the dough rise and become light.
- Flour
- Provides gluten, the protein network that gives the dough structure to trap gas and set when baked.
- Lard
- Adds fat that tenderises the crumb and gives the rolls a softer texture.
- Salt
- Controls yeast activity and adds flavour to the dough.
The step that matters
Let the sponge and dough rise until light. Yeast needs warmth and time to produce enough gas to lighten the dough. Under-proofed dough bakes dense, while over-proofed dough can collapse and lose structure.
“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.
