Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the oven
Preheat the oven to 350°F (175°C).
Make the dough
Rub the butter into the flour.
Add the cream of tartar.
Dissolve the baking soda in the milk and add it to the flour mixture.
Roll out the dough and cut it into cakes.
Bake
Bake the cakes on tins in the preheated oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baking soda
- Reacts with the acidic cream of tartar to release gas, helping the cakes rise.
- Cream of tartar
- Acidic ingredient that reacts with baking soda to create lift and a tender crumb.
- Butter
- Coats flour particles when rubbed in, tenderising the dough and adding richness.
- Flour
- Provides the structure that sets as the cakes bake.
- Milk
- Provides liquid that hydrates the flour and dissolves the baking soda.
The step that matters
Dissolve the baking soda in the milk and add it to the flour mixture. Baking soda must be fully dissolved so it reacts evenly with the acid in the cream of tartar. Unevenly distributed soda can leave bitter pockets and uneven rising.
