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

  1. Preheat the oven to 400°F (200°C).

Make the dough

  1. In a bowl, mix the flour, baking powder, and salt.

  2. Rub in the lard until the mixture resembles breadcrumbs.

  3. Stir in the sugar and currants.

  4. Add the beaten egg and enough milk to form a stiff paste.

Bake

  1. Place small pieces of the mixture on a greased baking sheet.

  2. Bake for 20 minutes.

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 buns together as they bake.
Lard
Rubbed into the flour, it shortens the dough and gives a tender, crumbly texture.
Egg
Binds the mixture and adds richness and structure to the stiff paste.
Baking powder
Releases gas during baking, helping the buns rise and become light.
Currants
Add fruity sweetness and small pockets of chewy texture throughout the bun.

The step that matters

Rubbing in the lard. The fat must be worked into the flour until it resembles breadcrumbs so it coats the flour particles. This limits gluten development and keeps the buns short and crumbly rather than tough.

Swap the currant

How well each one fits the dish's main ingredients (flour, sugar, egg, milk):

  1. Vanillafits better
  2. Raisinfits better
  3. Figfits better
  4. Currantthe original

Fit is the average pairing score against flour, sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
