Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Oream- or Spice Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make and bake the batter
In a bowl, mix the sour cream and sugar until well combined.
Add the flour, baking soda, egg, and mixed spice; stir until smooth.
Pour the batter into a greased cake pan.
Bake for 30-35 minutes or until a toothpick comes out clean.
Cool
Let cool before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour cream
- Adds moisture and tang, keeping the crumb tender and moist.
- Flour
- Provides the structure that holds the cake's shape as it bakes.
- Baking soda
- Reacts with the acidic sour cream to produce gas that lifts the batter.
- Egg
- Binds the batter and adds structure and richness to the crumb.
- Sugar
- Sweetens the cake and helps brown the crust and tenderize the crumb.
The step that matters
Stirring the batter until smooth. Once the flour is added, overmixing develops gluten, which can make the cake tough and dense. Stir only until the batter is smooth.
