Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Railroad 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

  1. Preheat your oven to 350°F (175°C).

Make the batter

  1. Beat the sugar and egg yolks together until well combined.

  2. Whisk the egg whites until frothy and fold them into the mixture.

  3. Mix the cream of tartar with the flour.

  4. Dissolve the baking soda in a small amount of water or milk and add it to the batter.

  5. Combine all ingredients until smooth and pour into a greased baking pan.

Bake

  1. 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
Egg whites, whipped to froth, add lift and an airy structure to the batter.
Baking soda
Reacts with the cream of tartar to release gas, helping the cake rise.
Cream of tartar
Acid that reacts with the baking soda and stabilizes the whipped egg whites.
Flour
Provides the starch and protein that set the cake's structure as it bakes.
Sugar
Sweetens the cake and helps tenderize the crumb.

The step that matters

Folding in the egg whites. Folding gently keeps the whipped whites' air intact. Stirring vigorously would deflate the foam, leading to a denser, flatter cake.
