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 ↓
A Delicious Cream-cake and Sweet Rusks
Ingredients
Directions
The book gives no oven temperature. The 350°F in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Crumble the butter into the flour.
Mix in the sugar, salt, and candied citron or orange rind.
Add the sour cream and whisked eggs, mixing until smooth.
Before pouring into buttered molds, blend in the carbonate of soda with an equal amount of sugar and flour.
Bake and finish
Fill the molds two-thirds full and bake in a moderate oven (350°F / 175°C) for about 45 minutes.
For rusks, pull apart the cake while hot and return to the oven to crisp.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Coats the flour and adds richness and tenderness to the crumb.
- Fine flour
- Provides the structure that holds the cake together as it bakes.
- Sugar
- Adds sweetness and helps brown the crust.
- Sour cream
- Adds moisture and acidity, giving a tender, moist crumb.
- Eggs
- Bind the batter and add structure and richness as they set.
- Carbonate of soda
- Reacts with the sour cream's acidity to lift and lighten the cake.
The step that matters
Blending in the carbonate of soda. Soda must be evenly distributed through the batter, and it reacts with the sour cream's acid to produce rise. Mixing it in just before the molds are filled, with sugar and flour to spread it evenly, keeps the leavening active and prevents pockets of soda or uneven rising.
