Place the smoothie,egg yolks, corn starch, rice flour, salt and oil into a bowl and mix into a paste.
Whip the egg whites with the cream of tar tar till stiff peaks are formed. (Kitchen Aid #6, 5 minutes), add the stevia.
Fold in the egg whites into the egg yolk mixture 1/3 at a time.
Pour this into a 8 inch or tube pan and bake for 60 minutes at 170C.
Remove from the pan only when it is completely cooled.
