Mixing

Separated-egg sponge

Panning and Baking

One recipe is enough for one full-size sheet pan. Use one of two methods for sponge sheets:

1. Using a pastry bag with a medium plain tip, pipe the sponge mix in diagonal lines on a sheet pan lined with parchment. Pipe the strips of batter so they touch each other and so the entire pan is filled with the sponge batter.
2. Alternatively, simply spread with a palette knife.

Bake at 375°F(190°F) for about 10 minutes.
