Ingredients

Directions

The book says “a good 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. Mix the flour and fat by rubbing them together with your fingertips.

  2. Add the salt, sugar, currants or sultanas, baking powder, and candied peel.

  3. In the center, drop in the egg and milk, then mix lightly with a fork.

Bake

  1. Place rough heaps of the mixture on a greased baking sheet, leaving half an inch between each.

  2. Bake for about 20 minutes until golden brown.

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 structure that holds the buns together as they bake.
Fat (lard, dripping, or margarine)
Rubbed into the flour to make the buns tender and short rather than tough.
Egg
Binds the mixture and adds richness and structure to the dough.
Baking powder
Releases gas during baking so the buns rise and become light.
Moist sugar
Adds sweetness and helps the crust brown during baking.

The step that matters

Mixing in the milk and egg. Mix only lightly with a fork until just combined. Overworking the dough develops gluten, which makes the buns tough instead of tender.

Swap the currant
