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.
Make the batter
Cream together the butter and sugar until smooth.
Add the flour and egg whites, mixing well.
Dissolve the cream of tartar and baking soda in the sweet milk, then add to the mixture.
Bake
Season to taste and pour into a prepared baking pan.
Bake at 350°F (175°C) for 1.5 hours.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and give the cake a tender, rich crumb.
- Sugar
- Creams with butter to add sweetness and help hold air bubbles for a lighter texture.
- Flour
- Provides the main structure that sets as the cake bakes.
- Egg whites
- Add structure and lift through their proteins, which set during baking.
- Cream of tartar
- Stabilises the egg whites and reacts with baking soda to help the cake rise.
- Baking soda
- Reacts with the acidic cream of tartar to produce gas that leavens the batter.
The step that matters
Dissolving the cream of tartar and baking soda in the milk. Baking soda and cream of tartar must be evenly dispersed so the acid and base react throughout the batter, giving an even rise without bitter pockets or dense spots.
