Railroad Cake

Ingredients

Directions

Prepare

  1. Sift the flour three times before measuring.

  2. Measure 2 cups of flour and sift it with the baking powder into a bowl.

Make the batter

  1. Add the sugar without stirring.

  2. Make a depression in the center and drop in the unbeaten eggs.

  3. Melt the butter and pour it over the eggs.

  4. Gradually add the milk while stirring and beat until light and creamy.

  5. Flavor with vanilla. If the batter is too thick, add more milk a little at a time.

Bake and finish

  1. Bake in a loaf pan and cover with boiled icing.

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

What each ingredient does

All-purpose flour
Forms the main structure of the cake as its proteins set during baking.
Eggs
Add structure and richness, and help bind the batter together.
Baking powder
Releases gas during baking, helping the cake rise and become light.
Butter
Adds fat for a tender crumb and rich flavor.
Milk
Adds moisture and loosens the batter to a smooth, pourable consistency.
Sugar
Adds sweetness and helps keep the crumb tender and moist.

The step that matters

Gradually add the milk while stirring and beat until light and creamy.. Adding liquid slowly lets the batter blend into a smooth emulsion without curdling, and beating traps air that helps the cake rise evenly.

Swap the vanilla

How well each one fits the dish's main ingredients (flour, sugar, egg, butter, milk):

  1. Vanillathe original
  2. Raisinfits about as well
  3. Figfits less well
  4. Coconutfits less well

Fit is the average pairing score against flour, sugar, egg, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
