Lemon Biscuits

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. Rub the flour into the butter.

  3. Stir in the pounded sugar and finely minced lemon peel.

  4. Add the eggs, which should be well whisked, and the lemon juice.

  5. Beat the mixture well for 1-2 minutes.

Bake

  1. Drop spoonfuls of the mixture onto a buttered baking sheet, about 2 inches apart.

  2. Bake for 15-20 minutes until the biscuits are a pale brown.

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 biscuits once mixed with the eggs and butter.
Butter
Adds fat that tenderises the dough and carries flavour.
Eggs
Bind the mixture and add structure and lift as they are whisked in.
Loaf sugar
Adds sweetness and helps the biscuits brown lightly in the oven.
Lemon peel
Supplies the aromatic oil that gives the biscuits their lemon flavour.

The step that matters

Beat the mixture well for 1-2 minutes. Beating the whisked eggs into the dough incorporates air, which gives the biscuits lift and a lighter crumb. Under-beating leaves them dense, while over-working can toughen them.

Swap the lemon
