I created this sauce during a craving for a prawn cocktail, but being on a diet a mayonnaise rich sauce was a no-no. So I had a little play in the kitchen and this was the result. I will admit that this cannot recreate the creaminess of the real deal, but once spooned onto prawns and crisp lettuce I forget that it is a substitute. All measurements are very approximate, it is more a matter of finding a satisfactory consistency and tasting as you go.
