In short, practice run, a bit of a disaster.
I decided to go with the following recipe:
Mayonnaise
Pickle Relish
Australian Mustard with some seeds for texture
Salt
Pepper
Pimento Olives halved for garnish
It tasted perfect before I decided to add extra of everything after thinking back to one of the recipes I had read which indicated that due to the egg white it was best to make it tastier. Fail.
Will need to keep to the subtle, less of everything recipe for the real deal.
And will need to play around with presentation.
Need some lettuce or parsley. I've also noticed 1950's finger food was always very orderly, so was thinking of arranging in a circle but would need to place olives and pickles in the middle.
