Ingredients (for 21cm Tube Pan):
For egg yolk mixture
4 egg yolks
33g caster sugar
47g vegetable oil
67g plain flour
1/4 tsp baking powder
1/8 tsp salt
57ml mango yogurt drink
For egg white mixture
4 egg whites
1/8 tsp cream of tartar
47g caster sugar
Directions:
1. In a mixing bowl, beat together egg yolks and sugar until the mixture turns light & fluffy.
2. Add in oil and continue the beating until mixture turn pale.
3. Add in mango yogurt drink & mix to combine.
4. Add in plain flour, baking flour & salt and mix until the flour is just incorporated. Scrape the bowl and mix one final time before setting it aside.
5. In another clean mixing bowl (very important to ensure that there is no drips of egg yolk or oil in this bowl), whisk egg whites until they turn foamy.
6. Add in cream of tartar & whisk until soft peaks form.
7. Gradually add in sugar & whisk until stiff peaks form. Do not overbeat else the meringue will turn watery.
8. Transfer one-third of the meringue into the egg yolk mixture, beat it in. This will stabilize the mixture.
9. Gently fold in the remaining meringue in two batches.
10. Once no white streaks remains, pour the batter into an UNGREASED tube pan.
11. Lift the pan aabout 10cm off the table top, drop it vertically onto the table to remove any larger air bubbles.
12. Bake at 150 degree C for 40 minutes. The cake tends to crack if the temperature is too high.
13. Once the cake is done, invert it immediately & cool it on a wire rack. Do not unbold the cake until it has completely cool down.
