Grab a bowl and place your egg whites in and leave them to stand for around 30 minutes.
While you're waiting, sift 1/2 cup of sugar and the flour and set to one side.
Preheat oven to 350F.
Get your egg whites and add the cream of tartar, flavor extracts, and salt. Mix well unto you reach soft peaks. Now add the remaining cup of sugar slowly, continually beating as you add.
Now it's time to fold in your sifted flour mixture from earlier.
Spoon into a pan and bake for around 35-50 minutes.
Invert pan once out of the oven and leave to cool for around one hour.
