Why it works: Sugar and cinnamon are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 30,779 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the dough
Combine raised dough, salt, sugar, egg, butter, and lard.
Knead the mixture like bread.
Let it rise until light, then knead again.
Bake
Before baking, spread butter on top and sprinkle with sugar and cinnamon.
Bake in a moderate oven (350°F / 175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raised dough
- Provides the yeasted structure that rises and gives the cake its bread-like crumb.
- Butter
- Adds richness and moisture, and browns on top for flavor and color.
- Lard
- Adds tenderness and a soft, short texture to the dough.
- Egg
- Enriches the dough, adding structure and a tender crumb.
- Sugar
- Sweetens the dough and caramelizes on top for browning.
The step that matters
Let it rise until light, then knead again. The dough must rise fully before the second kneading so the yeast has built enough gas and structure. Under-proofed dough bakes dense, while the second knead redistributes the gas and firms the crumb.
Swap the cinnamon
How well each one fits the dish's main ingredients (sugar, egg, butter):
- Cinnamonthe original
- Nutmegfits about as well
- Capersfits less well
- Parsleyfits less well
Fit is the average pairing score against sugar, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
