If you combine equal amounts of beef and chicken broth, you will have a mock veal broth. It is a little stronger then chicken, but not as overtaking as beef. I have done this many times.
Veal bones are very hard to find. So this is a second choice. And should you in error use the wrong broth, as our first poster did, you can correct it very easily to a pleasant tasting broth.
