Cochineal Marble 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 the batter

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

  2. Cream the butter and powdered sugar together until smooth.

  3. Beat the egg whites until frothy.

  4. Gradually combine the egg whites with the butter and sugar mixture.

Marble and pour

  1. Soak the cochineal in hot water, bruise it, and strain it into three-fourths of a teacup of the cake batter.

  2. Pour the batter into the cake tin, marbling with the red dough as you go.

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

What each ingredient does

Butter
Adds richness and tenderness, as its fat coats the flour and limits toughness.
Powdered sugar
Sweetens the cake and, creamed with butter, helps trap air for a lighter crumb.
Flour
Provides the structure that sets as the cake bakes.
Egg whites
Whipped into foam, they add lift and help set the crumb.
Baking powder
Releases gas when heated, helping the cake rise.
Cochineal
Natural red colouring that gives the marbled swirls their colour.

The step that matters

Gradually combining the egg whites. Whipped egg white foam traps air that makes the cake light. Adding it gradually and folding gently keeps that foam from collapsing, while overmixing deflates it and yields a denser cake.
