Got the original recipe for this fifteen years ago from an ethnic cookbook. The author's Hungarian grandmother taught her how to make it so I'm sure it's one authentic way to make goulash. It's so good it's worth the effort it takes to make and much of the time you can be doing other things while it simmers. Just keep an eye on it and stir once in awhile. I like to serve it with steamed beet greens or spinach dressed with a bit of butter, salt/pepper and vinegar.
