Why it works: Sugar and cream 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 ↓
Sour Cream 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.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and eggs until light and fluffy.
Mix in the sour cream until well combined.
In another bowl, whisk together the flour, baking powder, baking soda, salt, and mace.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Bake and ice
Pour the batter into a greased cake pan and bake for 25-30 minutes or until a toothpick comes out clean.
For the icing, beat the reserved egg white until stiff peaks form.
Squeeze the juice of half a lemon into the egg white and gradually add confectioner's sugar until the desired consistency is reached.
Fold in the melted chocolate gently until combined.
Spread the icing over the cooled cake.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Eggs
- Bind the batter and whip the egg white to make a stable icing.
- Sour cream
- Adds moisture and tenderness to the crumb.
- Flour
- Provides the structure that holds the cake together.
- Baking powder
- Releases gas to lift the batter as it bakes.
- Sugar
- Sweetens the cake and helps give it a light, fluffy texture when creamed.
- Melted chocolate
- Adds flavor and color to the icing.
The step that matters
Gradually add the dry ingredients to the wet mixture, stirring until just combined.. Overmixing once flour is added develops gluten, which makes the cake tough and dense. Stir only until no dry flour streaks remain.
Swap the mace
How well each one fits the dish's main ingredients (sugar, egg, cream, flour, lemon, chocolate):
- Nutmegfits better
- Cinnamonfits better
- Peppermintfits better
- Macethe original
Fit is the average pairing score against sugar, egg, cream, flour, lemon, chocolate. Candidates are from the same food group and used in at least 100 recipes.
