Ladyfinger Sponge (Biscuit Cuillère)

• 1. Whip up the egg whites gradually adding the sugar in 3 portions until stiff.

  2. Fold in the egg yolks.

  3. Sift in the flour bit by bit, dusting the surface of the batter and folding it in gradually.

  The most convenient way to sift flour in advance is to sift it onto the baking sheet the sponge is going to be baked on and transfer it back to a container then.

• 4. Pipe into desired shape.
  
• 5. Bake at 180°C for 8-10 minutes.
