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
Preheat the oven to 400°F (200°C).
In a bowl, mix the flour, sugar, cream of tartar, and baking soda.
Make the batter
Add the well-beaten eggs to the dry ingredients.
Melt the butter in a small cup of milk and add to the mixture.
Stir well for a few minutes until combined.
Pour the batter into two well-buttered round cake tins.
Bake and serve
Bake in the preheated oven until done, about 20-25 minutes.
Cut open, butter, and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the main structure of the cake as its proteins set during baking.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Cream of tartar
- Acidifies the batter so baking soda reacts and helps the cake rise.
- Baking soda
- Reacts with the acidic cream of tartar to release gas that lifts the batter.
- Butter
- Adds fat for tenderness and flavour and helps the cake brown.
- Sugar
- Sweetens the cake and contributes to browning and a tender crumb.
The step that matters
Stir the batter only until combined. Stirring for a long time develops gluten in the flour, which can make the cake tough. Mixing just until combined keeps the crumb tender while the leavening, activated by the cream of tartar and baking soda, still lifts the batter.
