Mix the egg yolks with sugar.
Stir in oil and yuzu yogurt smoothie drink. Combine well.
Sift in the cake flour, baking powder.
Stir into egg yolk mixture. It should be no lumps inside.
Use a large mixing bowl, beat the egg whites with an electric mixer until bubbles. Add cream of tartar and mix well. Add in sugar in three batches, about one-third at a time. Beat well between additions. Continue to beat until stiff peaks form.
Lightly fold-in the meringue into the egg yolk mixture in three batches until just combined.
