So is there a such thing as kosher pizza? I really like to go to a local dive bar here and they have awsome tasting pizza, I realize that it is forbidden to mix meat with cheese but what if it is just pizza with veggies or just cheese?
Oy Vey!!! Since when are Jews relying on the ingredients list to see if something is kosher or not?
Since the Talmudic times perhaps?
If you go to Rav Abadi's website kashrut.org and post up the ingredients of a packaged food that doesn't have a hechsher, they will tell you if it's kosher or not based on the ingredients. Now, it's true there may be a big difference with a "fast food" type of situation where it's not a packaged food with a label of ingredients. Sure. He can't just assume pizza like that is kosher because they are definitely cooking meat in the oven with it. But for a packaged food, what you said is simply not true. No offense, but you really don't know what you're talking about.
Unlees you prepare it yourself, you must assume that any food is NOT Kosher if it has no Ortodox Rabbinical Certification.
Again, this is not true, however I agree if you're saying he shouldn't eat the pizza from the non-kosher place - that would indeed be mistaken. But otherwise there can be kosher foods that don't have certification. A person should go to kashrut.org and ask the Rabbi Abadi and his sons if they are not sure, to confirm whether or not the food in question is kosher. Rav Abadi was the renown posek of Lakewood for some time and has an expertise in kashrut for american Jews.
BTW, Gentiles' cheese is generally forbidden to Jews because it might have renet, and in most communities, simply because the cow was not milked by a Jew, so it's not Cholov Yisroel.
2 different issues.
Rennet is from the cow's intestine. So it's combining meat and dairy (I guess).
Cholov Yisrael is a stringency that not all Orthodox Jews keep and is not mandatory for an American Jew to hold by. If a Jew has milk or cheese that is not cholov yisrael, it can still be kosher even if he's not keeping that higher standard. There's a big difference between something actually being not kosher vs. not adhering to the highest level of stringency.
