Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the batter

  1. Beat the eggs until well combined.

  2. Dissolve the cream of tartar in hot water and let it cool.

  3. Combine the cooled mixture with the eggs and beat for 10 minutes.

  4. Add the sugar and flour, mixing until smooth.

Bake

  1. Pour the batter into square tins.

  2. Bake in a 400°F (200°C) oven until golden.

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

What each ingredient does

Eggs
Provide structure and lift through the foam they trap when beaten.
Cream of tartar
Its acidity helps stabilise the beaten eggs so the foam holds.
Sugar
Adds sweetness and helps give the cake a tender crumb.
Flour
Sets the structure of the cake as the batter bakes.

The step that matters

Let the cream of tartar mixture cool before combining it with the eggs. Hot liquid can warm and deflate the beaten egg foam, weakening the rise the batter relies on. Letting it cool keeps the foam intact when the two are beaten together.
