Variegated Cakes

Ingredients

Directions

Make the batter

  1. Cream the butter with the powdered sugar.

  2. Add the milk, almond flavoring, whipped egg whites, and flour.

  3. Divide the batter into three parts.

Color the batter

  1. Bruise spinach leaves in thin muslin bags to extract juice.

  2. Add a few drops of spinach juice to one portion.

  3. Color another portion with cochineal.

  4. Leave the third portion white.

  5. Pound pistachio nuts for the green batter for added flavor.

Layer and finish

  1. Spoon a little of each color into small round pans or cups.

  2. Stir slightly as you add each color to create a veined effect.

  3. Layer the white batter between the pink and green for better color contrast.

  4. Ice the sides and top of the cakes.

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

What each ingredient does

Butter
Creaming with sugar traps air, giving the cake a tender, light crumb.
Powdered sugar
Sweetens the batter and helps create a fine, tender texture when creamed with butter.
Eggs
Whipped whites add air and lift, helping the cakes rise and stay light.
Prepared flour
Forms the main structure that sets the cake as it bakes.
Milk
Adds moisture and liquid so the flour hydrates into a smooth batter.

The step that matters

Stir slightly as you add each color. Light stirring lets the colored batters swirl into veins; overmixing blends them into a uniform tint and loses the marbled effect, while the whipped whites can deflate if handled roughly.

Swap the pistachio

The recipe marks pistachio as optional. How well each one fits the dish's main ingredients (sugar, butter, milk, egg, flour, almond, spinach):

  1. Cashew nutfits about as well
  2. Pistachiothe original
  3. Chestnutfits less well
  4. Hazelnutfits less well

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