Here is the situation...I ran into an old professor who is also a Rabbi. He taught a comparative religion class that I had over 15 years ago. I invited him and his family over to my house for dinner. I have a few weeks to prepare. His parting words to me were...make sure it is Kosher. My wife wants to make Pho, which is a Vietnamese beef noodle soup that is quite good. How do I make sure all of the ingredients are Kosher? I know some stuff in stores is marked Kosher but what about the stuff that isn't? I would like to make an appropriate 5 course meal. Anybody know where I can buy Kosher beef? I want to order some beef from Lobel's but I am sure that it isn't Kosher. If anybody can point me in the right direction, I would be most appreciative.
