And your description of that spread sounds awful; especially compared to the for real Liptauer one. So please DO try the posted authentic Hungarian recipe IF you think it might be something you'd enjoy eating. :-)
There is no such thing as Viennese Cheese - I explained how the name came about. I don’t really do these type of things, anyway, the closest I’ve come is Lipton’s Onion Dip with sour cream. Interestingly, people fall all over that stuff when I have it at parties. Same with Pigs in a Blanket. No matter how snobby people are, they love American-style appetizers even while sneering at it. Never fails!
