Biscuits Legers

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 the batter

  1. Separate the yolks of 5 eggs and place them in a pan.

  2. Add crisped orange flowers and finely shredded lemon peel.

  3. Mix in ¾ pound of fine sugar until dissolved.

  4. Beat the whites of all 10 eggs until frothy.

  5. Gently fold the beaten whites into the yolk mixture.

  6. Gradually stir in 6 ounces of flour.

Bake

  1. Pour the mixture into buttered molds and dust with fine sugar.

  2. Bake in a 350°F (175°C) oven until lightly golden.

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

What each ingredient does

Eggs
Beaten whites trap air that lightens the batter and sets into a delicate structure.
Fine sugar
Sweetens the batter and helps keep the crumb tender and moist.
Flour
Provides the structure that holds the risen batter together as it bakes.
Orange flowers
Adds a floral aroma that carries through the baked biscuits.
Lemon peel
Adds bright citrus aroma from the oils in the zest.

The step that matters

Gently fold the beaten whites into the yolk mixture. Beaten egg whites hold air bubbles that give the biscuits their lightness. Vigorous stirring deflates them, so fold slowly with a broad motion to keep the batter airy.

Swap the orange
