BASE 2
8 egg whites
3/4 c white sugar
1 tsp cream of tartar

Place egg whites and cream of tartar into the mixing bowl. Using wire whisk, shift the mixer to 5 until it resembles to a float/bubbly(like beer). Gradually add in sugar. Whisk until soft peaks form. NOTE: Do not over mix, the consistency of the white should be like shaving cream, not dry and a little bit stiff.

Fold the cake flour into the white mixture by using rubber spatula.

Put the batter into the greased lined pan and tap once onto working table to release air bubbles.

Bake at 350F for 30 mins. Turn the pan upside down, and peel the paper. Let it cool.

NOTE: you can also roll this cake as in jelly roll. As soon as you take the cake out of the oven, roll it w/ the paper inside. Set aside while you prepare your own filling. Otherwise, you can slice it like a cake, put some fruits and some whip cream. Enjoy.
