  Mix the two mixtures of egg yolks and egg whites

  To make the egg yolk mixture less thick, add 1/3 of the whipped egg whites from the previous step into the egg yolk bowl, then use a whisk to mix it well.

  Continue to add another 1/3 of the remaining egg white mixture into the bowl, using the “fold” technique to combine the two mixtures until you achieve a smooth fluffy mixture.
