The Pink Whisk Guide to Cake Making. Ruth Clemens

important to do it step by step and whisk the air back into the mixture before adding the next drop of egg. Keep working this way until all of the egg is incorporated and you have a light and fluffy mixture – still packed with the air bubbles you’ve been working in (and not a sign of curdling!). If the air isn’t worked back in after each addition the mix will be very liquidy and will have lost all the oomph you gave it in the creaming stage. For the best cakes it’s worth spending the time doing it slowly.
