Why it works: Flour and butter 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 ↓
French Rolls
Ingredients
Directions
The book says “a brisk oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the sponge
Dissolve one-third of a cake of yeast in ½ cup of lukewarm water until soft.
Stir in flour to make a thick batter and let it sit overnight.
Make the dough
In the morning, mix the yeast with 2 pints of flour, sugar, salt, butter, and lukewarm water.
If desired, add the beaten egg for richness.
Knead the dough and let it rise until doubled in size.
Shape and bake
Shape into rolls and place on a baking sheet.
Bake in a preheated oven at 350°F (175°C) until golden brown.

Flour and butter 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
- Flour
- Forms the gluten network that gives the dough structure and lets it hold its shape.
- Yeast
- Produces carbon dioxide as it ferments, making the dough rise and become airy.
- Sugar
- Feeds the yeast and helps the rolls brown in the oven.
- Butter or cottolene
- Adds fat that tenderizes the crumb and softens the texture.
- Egg
- Adds richness, color and tenderness to the dough.
The step that matters
Knead the dough and let it rise until doubled in size. Kneading develops gluten so the dough can trap gas. Letting it rise until doubled lets the yeast fill the dough with air; underproofing gives dense rolls, while overproofing can collapse them.
