concerned_sib: My sister who is religious would not eat anything in my house although I bought Kosher how can I accomodate her?

Rabbi Shlomo Chein: are you close to her?

concerned_sib: we talk once a month over the phone

Rabbi Shlomo Chein: I see you are trying to accomodate her, so let me try to explain why she did not want to eat.

Rabbi Shlomo Chein: firstly, it is nothing personal, I am sure she loves you, as you love her

concerned_sib: I know that

Rabbi Shlomo Chein: now, with regard to Kosher food, it is more than just the ingredients - it is also how it is prepared. So say you go out of your way and kindly by some kosher chicken, but then cook it in the same oven that is used to cook non-kosher chicken, that chicken is now non-kosher too

concerned_sib: But she wouldn't eat on my dishes with kosher take out, how is that a problem?

Rabbi Shlomo Chein: i am glad you brought that up. Since your dishes are you used for non Kosher food (particularly hot non kosher food) your dishes too are not kosher according to Jewish law. (by the way it is really nice of you to go so far out of your way to get takeout etc.)

Rabbi Shlomo Chein: if you want, you can use disposable dishes

concerned_sib: ok

concerned_sib: Thanks

concerned_sib: you've been a great help!\

Rabbi Shlomo Chein: my pleasure - all the best
