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.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a mixing bowl, beat the sugar and butter together until creamy.
Dissolve the baking soda in the cold water.
Sift the cream of tartar into the mixture and mix well.
Add the flour and the dissolved baking soda mixture to the creamed butter and sugar. Mix until well combined.
Bake
Pour the batter into a greased cake pan and bake 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, rich crumb.
- Sugar
- Creams with butter for aeration and adds sweetness and browning.
- Flour
- Provides the structure that sets the cake as it bakes.
- Eggs
- Add structure, richness and moisture to the batter as it sets.
- Baking soda
- Reacts with the acidic cream of tartar to release gas that helps the cake rise.
- Cream of tartar
- Acid that activates the baking soda, helping the cake rise and stay light.
The step that matters
Dissolving the baking soda in the cold water. Baking soda must be fully dissolved so it spreads evenly through the batter; clumps can leave bitter spots and uneven rising. It reacts with the acid in the cream of tartar, so the batter should be baked soon after mixing to keep the lift.
Swap the vanilla
How well each one fits the dish's main ingredients (sugar, flour, butter, egg, cream):
- Vanillathe original
- Raisinfits about as well
- Coconutfits less well
- Figfits less well
Fit is the average pairing score against sugar, flour, butter, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
