Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, mix the egg yolks and pulverized sugar until well combined.
Cream the butter and add it to the mixture.
Dissolve the baking soda in the sour cream and add it to the bowl.
Gradually add flour until the dough is easy to roll.
Shape and bake
Shape the dough into cakes and place them on a baking sheet.
Sprinkle sugar and cinnamon over the tops of the cakes before baking.
Bake in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and help bind the dough together.
- Butter
- Adds fat for tenderness and a rich flavour.
- Baking soda
- Reacts with the sour cream's acidity to lift and lighten the cakes.
- Sour cream
- Its acidity activates the baking soda and adds moisture.
- Flour
- Provides structure so the dough can be rolled and shaped.
The step that matters
Dissolve the baking soda in the sour cream. Baking soda needs an acid to react and produce gas. Dissolving it fully in the sour cream spreads the reaction evenly through the dough, so the cakes rise uniformly instead of in patches with bitter spots.
Swap the cinnamon
How well each one fits the dish's main ingredients (egg, sugar, butter, cream, flour):
- Nutmegfits better
- Cinnamonthe original
- Capersfits less well
- Jalapenofits less well
Fit is the average pairing score against egg, sugar, butter, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
