Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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.
Prepare the dough
Peel and boil the potatoes until soft.
Pass the potatoes through a colander with the milk.
Mix in enough flour to achieve a muffin-like thickness.
Add the homemade yeast and let it stand for 4 hours.
Stir in sufficient flour to make a stiff bread dough.
Shape, rise and bake
Mold the dough and place it in pans.
Let it rise for 3 hours.
Bake in a preheated oven at 400°F (200°C) for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Add starch and body, giving the cake a soft, moist crumb.
- Flour
- Provides the structure that holds the stiff dough together as it bakes.
- Homemade yeast
- Produces gas as it ferments, causing the dough to rise and lighten.
- Milk
- Adds moisture and richness, helping the dough stay soft and tender.
- Butter
- Adds fat for tenderness and flavour, and gives gentle browning in the oven.
The step that matters
Letting the dough rise fully before baking. Yeast needs time to produce enough gas to lighten the dough. If the rise is cut short, the cake bakes up dense; if over-proofed, it can collapse and lose structure.
