Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Cream Sponge 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 the batter

In a bowl, break the eggs and add heavy cream.
Add sugar, flour, cream of tartar, baking soda, and vanilla extract.
Mix until smooth and well combined.

Bake

Pour the batter into a greased cake pan.
Bake for 25-30 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs: Provide structure and richness as they set during baking.
Heavy cream: Adds moisture and fat, giving the cake a tender crumb.
All-purpose flour: Forms the main structure of the cake as its proteins set in the oven.
Cream of tartar: Stabilizes the egg mixture and helps the leavening react for a lighter rise.
Baking soda: Reacts with acidic ingredients to produce gas that helps the cake rise.
Sugar: Sweetens the cake and helps keep it moist and tender while browning.
