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 ↓
6-egg Sour-cream Pound Cake
Ingredients
Directions
Prepare and mix the batter
In a bowl, cream butter.
Gradually beat in sugar until light and fluffy, about 5-7 minutes.
Add egg yolks, one at a time, beating well after each addition.
Combine flour, baking soda, and salt; add to creamed mixture alternately with sour cream and vanilla.
Beat on low just until blended.
Beat egg whites in separate bowl on high until stiff peaks form.
Fold egg whites into cake batter until blended.
Bake and cool
Spray baking oil in desired pan and sprinkle with sugar and cinnamon (nuts optional).
Pour cake batter into pan or fill with spoonfuls of batter until evenly spread.
Bake at 325°F for 1 hour and 25 minutes or until toothpick inserted in the middle comes out clean.
Cool in pan 15 minutes.
Slightly toss cake in pan to loosen edges then turn cake over onto plate and cool completely.
Optional icing
Optional icing: combine confectioners' sugar, water (1 teaspoonful at a time), and lemon juice or extract.
Stir until desired consistency—adding more water (1 teaspoon at a time).
Pour by spoon over cake, if desired.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Butter
- Creamed with sugar to trap air, giving the cake a tender, rich crumb and flavor.
- Eggs
- Yolks add richness and structure; whipped whites lighten the batter and help it rise.
- All-purpose flour
- Provides the main structure that holds the cake together as it bakes.
- Sugar
- Creaming with butter aerates the batter and adds sweetness and a fine, moist texture.
- Sour cream
- Adds moisture and tang, and its acidity works with baking soda for a tender crumb.
- Baking soda
- Reacts with the sour cream's acidity to produce gas that helps the cake rise.
The step that matters
Folding in the egg whites. Whites whipped to stiff peaks hold the cake's air. Folding gently keeps that air in; vigorous stirring deflates the batter and yields a dense cake.
Swap the vanilla
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, cream):
- Vanillathe original
- Raisinfits about as well
- Coconutfits less well
- Figfits less well
Fit is the average pairing score against butter, sugar, egg, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
