Make the mocha chiffon cake:

Sift together flour, 1/2 cup blended white sugar, baking powder and salt three times. Set aside.
Dissolve coffee in water and set aside.
-Put dry ingredients into a wide mixing bowl and make a well in the center.
Add egg yolk, oil, and coffee mixture. Mix with whisk until smooth. Set aside.
-In a mixing bowl with a wire attachment, beat egg whites with cream of tartar at high medium speed until frothy.
Add 1/4 cup blended sugar and increase speed to low-high until stiff peaks are formed but make sure they are not dry.
Fold in 1/3 of the egg white mixture into the yolk mixture to lighten.
Gently fold in the rest of the egg white mixture until blended.
Do not over mix.
