Snow 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

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

  2. Line the sides of a baking tin with buttered paper.

Make the batter

  1. Cream the sugar and butter together until smooth.

  2. Sift in the arrowroot and mix well.

  3. Whisk the egg whites to stiff peaks and gently fold them into the mixture.

  4. Add essence of lemon to taste and whisk the mixture for about 30 minutes.

Bake

  1. Pour the batter into the tin and bake until golden.

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

What each ingredient does

Arrowroot
Provides a light, tender starch structure that gives the cake its fine, delicate crumb.
Egg whites
Whisked to stiff peaks, they trap air and lift the batter for a light, airy texture.
Butter
Creamed with the sugar, it adds richness and a tender texture to the cake.
Sugar
Creamed with the butter, it sweetens the cake and helps build a smooth base for the batter.

The step that matters

Folding in the egg whites. Egg whites hold air only when whisked to stiff peaks. Folding gently keeps that air in the batter; stirring hard deflates it and the cake bakes up dense.

Swap the arrowroot

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

  1. Asparagusfits better
  2. Leekfits about as well
  3. Shallotfits about as well
  4. Arrowrootthe original

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