Ingredients
Directions
The book says “a sharp oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
In a large bowl, combine the flour, sugar, and ground spice.
Add the barm and mix well.
Gradually add milk until the mixture reaches a dough-like consistency.
Bake
Preheat your oven to 400°F (200°C).
Bake the mixture in the preheated oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake together.
- Sugar
- Adds sweetness and helps the crumb brown in the oven.
- Barm
- Acts as a leavening agent that helps the cake rise.
- Ground spice
- Gives the cake its aroma and flavour.
- Milk
- Adds moisture and brings the flour together into a dough.
The step that matters
Gradually add milk until the mixture reaches a dough-like consistency. Flour absorbs liquid at different rates depending on its moisture and how it was measured. Adding milk slowly lets you stop when the dough is right, since too much liquid makes it sticky and dense while too little leaves it dry and crumbly.
