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).

  2. Rub the dripping into the flour.

  3. Stir in the sugar and baking powder.

  4. Grate the lemon zest over the mixture.

  5. Beat the egg and strain in the lemon juice.

  6. Add the wet ingredients to the dry ingredients and mix into a stiff dough.

Shape and bake

  1. Knead the dough for a few minutes.

  2. Roll out the dough and cut it into small biscuits.

  3. Bake in the preheated oven for about 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms the structure of the dough once mixed with liquid.
Dripping or butter
Rubbed into the flour to add richness and a tender, crumbly texture.
Baking powder
Releases gas in the oven, helping the biscuits rise and become light.
Sugar
Adds sweetness and helps the biscuits brown lightly.
Lemon
Zest adds aroma and juice adds acidity that brightens the flavour.
Egg
Binds the dough and adds moisture and richness.

The step that matters

Rubbing the fat into the flour. Fat should be rubbed in until the mixture looks like fine crumbs. Coating the flour particles with fat limits gluten development, which keeps the biscuits tender rather than tough.

Swap the lemon
