Where did God come from?

I HAVE BEEN TOLD THAT DURING PASSOVER YOU CANNOT EAT ANYTHING MADE WITH SOURED MILK LIKE SOUR CREAM, BUTTERMILK, YOGURT, BAKING POWDER OR SODA ETC. ON THE OTHER HAND I HAVE BEN TOLD THAT THE SOURED MILK PRODUCTS MAY BE EATEN DURING PASSOVER AND UNLEAVENED BREAD. WHAT IS THE TRUTH? THANK YOU, CHARLOTTE

I have a personal question. My mother underwent a conversion when she was 20 years old, with the intent of becoming a Jew because she believes in Judaism and she also wanted a future with my father, a Jew. She studied for a year, did the mikveh, beis din before 3 torah-observing and shabbas-observing rabbis from JTS and everything. I understand that orthodox judaism does not recognize any of this. My question is I have been raised a Jew, had a kosher bris, bar mitzvahed, have studied briefly in a yeshiva, basically have expressed more interest than most jews i know and actually lived more than a year and a half as an observant Jew keeping shabbas and kashrus... Must i undergo a full conversion, from beginning to end (like a stranger on the street), as if all this i have done means nothing, or is there a quicker, symbolic conversion available for me, people like me... the name of which escapes me, but i know it has been given to people when it is unsure of the person's jewish status and in place of the standard full conversion. (like for the Falashas of Ethiopia). I think I would feel much better about all this if all i must do is a symbolic brit milah and immersion in mikveh... i feel less excited if it means i have to go through a year-long process as a matter of course. What, if any, are my options?

My son in law is allergic to nuts. How do I make the Haroset for the sedar. Someone suggested pine nuts. Is that kosher for passover. If not any suggestions

I'd like to know how to find out the date a part of the Babylonian Talmud was written. I'm not exactly sure how to properly reference it. I think it's Tract Sanhedrin - Haggada - Chapter 11 which is "THE HAGGADIC PART ABOUT RESURRECTION; SHARES IN THE WORLD TO COME; AND ABOUT THE MESSIAH, ETC.". The source I'm looking at can be found at http://www.sacred-texts.com/jud/t08/t0814.htm. And on that page, it's down at the end of "page" 302 and the beginning of "page" 303. How can I get a general (or even better, exact) idea of when that particular part was written? Thank you so much for any help you can provide. Mark
