Place egg yolks in a mixing bowl. With a manual hand whisk, whisk the yolks a little. Add in sugar and whisk to combine. Add in vegetable oil gradually, whisk to combine. Add the mango puree, lemon juice, whisk to combine. Sieve over the flour and whisk till the flour is fully incorporated. Do not over mix. Set aside.
In a clean, dry mixing bowl, beat egg whites with a handheld electric mixer on low speed until mixture becomes frothy and foamy. Add half of the sugar amount and turn to high speed and beat the mixture. Continue to add in the remaining sugar and beat until the egg whites reaches the soft peak stage.The soft peak stage is reached when the peaks of the whites curl over and droop slightly. The egg whites should appear smooth and glossy. (Do not over beat the whites still stiff, it is better to beat the whites still soft peaks for easy folding with the yolk batter.)
- Blend mango flesh, sugar, yoghurt until the mixture becomes smooth.
- With an electric mixer, whisk non-dairy whipping cream till stiff. Fold in the whipped cream to the mango mixture. Blend thoroughly.
