Why it works: Flour and cinnamon are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 17,341 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Moravian Coffee Cake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Combine warm mashed potatoes, homemade yeast, and white sugar in a bowl.
Let the mixture rise.
Mix in the egg and melted butter.
Add enough flour to form a dough.
Shape and bake
Place the dough into pans.
Smooth the dough with your hand.
Let the dough rise until very light.
Make deep holes in the surface with your thumb.
In each hole, place a small lump of butter, a pinch of cinnamon, and a generous amount of light brown sugar.
Bake in a 400°F (200°C) oven.
Serve 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
- Mashed potatoes
- Adds moisture and a soft, tender crumb to the dough.
- Yeast
- Produces gas that makes the dough rise and become light.
- Egg
- Adds structure and richness to the dough.
- Melted butter
- Adds fat for tenderness and rich flavor.
- Flour
- Provides the structure that holds the dough together.
The step that matters
Let the dough rise until very light. Yeast needs time to produce enough gas for the dough to expand. Under-proofed dough bakes dense, while the rise sets the light, airy texture of the cake.
Swap the potato
How well each one fits the dish's main ingredients (sugar, egg, butter, flour, cinnamon):
- Sweet potatofits better
- Arrowrootfits better
- Chivefits better
- Potatothe original
Fit is the average pairing score against sugar, egg, butter, flour, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
