French Biscuits

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Weigh three eggs and use that weight in flour.

  2. Weigh four eggs and use that weight in sugar.

Make the batter

  1. Mix the yolks of the eggs with the sugar for 30 minutes.

  2. Beat the egg whites until stiff and fold them into the yolk mixture.

  3. Gently fold in the flour.

Shape and bake

  1. Spoon the mixture into small shapes on a baking sheet.

  2. Sprinkle sugar over the top of each biscuit.

  3. Bake in a slow oven at 300°F (150°C) until lightly golden.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Eggs
Whites beaten to stiff foam trap air, giving the biscuits lift and a light structure.
All-purpose flour
Sets during baking to give the biscuits their firm, dry structure.
Granulated sugar
Sweetens the biscuits and, sprinkled on top, caramelises to add browning.

The step that matters

Folding in the beaten egg whites. Fold gently so the air trapped in the stiff whites is kept. Stirring hard deflates the foam, and the biscuits then bake flat and dense instead of light.
