Separate egg whites and weigh them out.
Sieve the dry ingredients
Beat the egg whites until they get fluffy and white then add a third of the sugar, which for 30 seconds, add another third, whisk 30 seconds and add the remaining.
Whisk until they form peaks (shaving foam consistency)
Add the dry ingredients and fold in by hand very gently.
Fold until the mixture appears glossy and all the dry ingredients have combined. The batter should start looking shiny in places and move slowly when tipping the bowl.
Pipe onto a baking tray on baking parchment.
Tap the trays on a surface to smooth out any
imperfections and get them flat and smooth.
Leave until they are dry to the touch (you can use a fan to speed up process).
Bake for 9-11 minutes on 150 c in a fan assisted oven.
Once cool fill with either Buttercream, Ganache or Jam.
