Why it works: Sugar and flour 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 ↓
Bread Made From Liquid Yeast
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the sponge
In a large bowl, combine the cooked potatoes, lard, sugar, and warm water.
Mix in enough flour to create a stiff batter.
Add the liquid yeast and mix well.
Let the mixture stand until evening, when it will be very light.
Make the dough
Work in more flour until it forms a rather hard dough.
Cover and let it stand overnight.
In the morning, mold the dough into 4 or 5 loaves.
Bake
Let the loaves rise for 45 minutes.
Bake in a preheated oven at 300°F (150°C) for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Add starch and moisture, giving the bread a soft, tender crumb.
- Flour
- Forms the gluten structure that traps gas and gives the loaves their body.
- Liquid yeast
- Produces carbon dioxide gas as it ferments, causing the dough to rise and become light.
- Sugar
- Feeds the yeast so it ferments more actively during the rise.
- Lard
- Adds fat that tenderizes the crumb and softens the texture.
The step that matters
Let the sponge stand until evening. The yeast needs time to ferment and build gas and flavor. Stopping early leaves the batter flat and dense, so it should look very light before more flour is added.
Swap the potato
How well each one fits the dish's main ingredients (sugar, flour):
- Arrowrootfits better
- Beetrootfits better
- Sweet potatofits better
- Potatothe original
Fit is the average pairing score against sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
