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 ↓

Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the sponge
Peel and slice the potatoes very thin, then boil them until soft.
Mash the potatoes to a fine pulp and gradually add the boiling water, stirring until a starch forms.
Let the mixture cool, then add the yeast to form the sponge.
Allow the sponge to sit in a warm place for 10 to 12 hours or overnight until light and frothy.
Shape and bake
Once ready, add flour and knead until a stiff mass forms.
Let the kneaded dough rise for 30 to 45 minutes.
Divide the dough into pans and let it rest for 15 minutes, ensuring it doesn't rise too much.
Bake in a 400°F (200°C) oven for about 45 minutes.

What each ingredient does
- Potatoes
- Provide starch and body that gives the bread a soft, moist crumb.
- Boiling water
- Gelatinizes the potato starch so it can bind and hold moisture.
- Yeast
- Ferments the sponge, producing gas that makes the dough light and frothy.
- Flour
- Forms gluten when kneaded, giving the dough structure to hold its rise.
The step that matters
Adding the boiling water to the mashed potatoes. Water must be added gradually while stirring so the potato starch gelatinizes evenly into a smooth paste; adding it all at once can leave lumps and uneven starch, which affects the dough's texture.
