Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Bread
Ingredients
Directions
Make the dough
Mix the hot mashed potatoes with lard, sugar, salt, and warm potato water.
Add flour and yeast, then beat well for five minutes.
Cover and let rise until doubled in size.
Knead and rest
In the evening, gradually add more flour, beating until too stiff to mix.
Knead until firm, then keep warm overnight.
Shape and bake
In the morning, place in buttered pans, let rise, and bake.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Add moisture and starch that keeps the crumb soft and moist.
- Flour
- Forms the gluten structure that traps gas and gives the loaf its body.
- Yeast
- Produces carbon dioxide during fermentation, making the dough rise.
- Lard or butter
- Adds fat that tenderizes the crumb and softens the texture.
- Sugar
- Feeds the yeast and promotes browning in the crust.
The step that matters
Beating in the flour until too stiff to mix. Gluten develops as flour is worked into the dough. Adding flour gradually and stopping once the dough is too stiff to mix keeps it workable, while kneading until firm builds the structure that holds the rise.
Swap the potato
How well each one fits the dish's main ingredients (butter, sugar, flour):
- Arrowrootfits better
- Shallotfits better
- Sweet potatofits better
- Potatothe original
Fit is the average pairing score against butter, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
