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 ↓

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, mix the sugar and beaten eggs until well combined.
Add the softened butter and mix until smooth.
In a separate bowl, combine the flour and cream of tartar.
Dissolve the baking soda in the water and add to the mixture.
Gradually add the flour mixture to the wet ingredients, stirring until just combined.
Add flavoring to taste.
Bake
Pour the batter into a greased baking 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
- Eggs
- Provide structure and richness as they bind the batter and set during baking.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Sugar
- Adds sweetness and helps keep the cake tender and moist.
- Butter
- Adds fat for a tender crumb and richer flavor.
- Cream of tartar
- Acidifies the batter and stabilizes the eggs for a lighter texture.
- Baking soda
- Reacts with the acidic cream of tartar to produce gas that helps the cake rise.
The step that matters
Stirring in the flour mixture. Once flour is added, overmixing develops gluten and can make the cake tough and dense. Stir only until just combined, leaving small lumps, so the texture stays light and tender.
