I've heard that even if kosher ingredients and equipment are used, the food cooked (i.e. using heat) by a Gentile isn't kosher in most circumstances. I am wondering what the opinions are regarding whether that also affects the equipment that is used.
This is specifically relevant to me: since I'm not Jewish, can I cook for myself in a kosher kitchen? But I'm not looking for a ruling; I would always ask permission from people regarding their own kitchens :) I just want a clearer idea about what should be asked.
