Helman's is too rich for me I prefer the cheaper and tarter salad cream but I do not think you can get that in the States.
Yes, you are right. We actually call a salad with meat and eggs and bacon bits, a Cobb Salad here. I've had a steak and romano cheese salad, which was really good. Generally, I can see why the concept of laying meat on top of lettuce would seem kinda gross, now that I think of it. It should be separate.
Salad Cream, huh? Forgive me, but it sounds kinda like you put it all in a blender and creamed it...or whipped cream is the other picture that comes to mind. Neither one would sound as good as salad "dressing" to me. Salad "dressing" sounds more like the proper "accessory" to a "well-dressed" salad - ha ha.
Yep, Miracle Whip sounds like our version of your tarter salad cream. There's many of us that feel the same way, here....put snugs on our Miracle Whip side ;-)
