Is this a sauce or is this a mayonnaise? Both actually!
My first encounter with this sauce was my mother making a tartare sauce this way, and actually this sauce is very close to tartare but different in that it has more herbs in it. I serve it the way I saw on Adam Liaw's show, as a bed for a chicken snitzel, but you could use the oil, mustard, lemon and egg yolks and just make mayonnaise with those.
When you make the mayonnaise, you do not have to drizzle it in like a normal mayonnaise, but if you just dump it all in it will split. So, just add it slowly mixing all the time.
I use chives and parsley but you can vary the herbs to whatever you like, try basil, thyme, tarragon or even celery or carrot tops.
This is really a very versatile sauce and goes really well with fish, chicken, or vegetables (think asparagus with sauce gribiche!) Once you have made it you will want to keep making it.
