Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Roll Breakfast Cakes
Ingredients
Directions
The book says “a rather quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Combine bread dough, butter, sugar, beaten egg white, baking soda dissolved in hot water, and cinnamon in a bowl.
Mix thoroughly, adding enough flour to make a stiff dough.
Shape and fill
Roll the dough to ¼ inch thick.
Spread the rolled dough with a mixture of ⅔ cup sugar and 1 beaten egg.
Roll up the dough like a jelly cake.
Cut the roll into 1-inch thick pieces.
Place the pieces on their ends in shallow tins.
Rise and bake
Let the pieces rise until very light.
Bake in a preheated oven at 400°F (200°C) until golden.
Serve warm or cold with coffee.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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
- Bread dough
- Forms the base structure that holds the rolled spiral shape while it rises and bakes.
- Butter
- Adds fat that softens the crumb and gives a richer, tender texture.
- Sugar
- Sweetens the rolls and helps the outside brown during baking.
- Egg white
- Adds protein that helps bind the dough and set its structure as it bakes.
- Ground cinnamon
- Provides the warm, spiced aroma that defines the flavour of the rolls.
The step that matters
Let the pieces rise until very light. Rising lets gas trapped in the dough expand the pieces before baking. Stopping too early leaves dense rolls, while over-proofing lets the structure collapse in the oven.
Swap the cinnamon
How well each one fits the dish's main ingredients (bread, butter, sugar, egg, flour):
- Nutmegfits about as well
- Cinnamonthe original
- Capersfits less well
- Parsleyfits less well
Fit is the average pairing score against bread, butter, sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
