Brown Bread 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. Separate the egg whites from the yolks.

Make the batter

  1. In a bowl, mix the yolks with sugar and lemon zest until light and white.

  2. Whisk the egg whites until stiff peaks form.

  3. Gently fold the egg whites into the yolk mixture.

  4. Sift the flour and mix it with the crumbled brown bread.

  5. Fold the flour mixture into the batter lightly.

Bake

  1. Pour the batter into small tins lined with parchment paper.

  2. Bake until golden and cooked through.

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

What each ingredient does

Eggs
Whipped whites give the biscuits lift and an airy structure, while yolks add richness and tenderness.
Sugar
Sweetens the batter and, creamed with the yolks, helps create a light texture.
Flour
Provides the structure that holds the biscuits together as they bake.
Brown bread
Adds body and a toasted, earthy flavour to the batter.
Lemon zest
Adds aroma and a bright citrus flavour that cuts the sweetness.

The step that matters

Folding the egg whites into the yolk mixture. Whipped whites hold air that gives the biscuits lift. Folding gently preserves that air, while stirring or overmixing deflates the batter and leaves the biscuits dense.
