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 ↓
Velvet 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
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Dissolve the baking soda in a little cold water and add to the mixture.
Sift the cream of tartar with the flour and gradually add it to the batter.
Flavor the batter with lemon to taste.
Bake
Pour the batter into a greased cake pan and 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
- Butter
- Creamed with sugar to trap air, giving the cake a tender, fine crumb and rich flavor.
- Eggs
- Add structure and richness as they set during baking, binding the batter together.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
- Baking soda
- Reacts with acidic components to release gas, helping the cake rise.
- Cream of tartar
- Acidic component that reacts with baking soda to help the cake rise and stay tender.
The step that matters
Dissolve the baking soda in a little cold water and add to the mixture.. Baking soda must be fully dissolved and evenly distributed so it reacts with the acid in the batter; clumps can leave bitter spots and uneven rising.
