I do not understand why some people keep chalav Yisrael today. Do they really think that someone is adding pig's milk? My friend quoted his rav that it is more important to keep chalav Yisrael today than it ever was before. How could this be?
May I place cold frankfurters on top of a hot pot to warm them on Shabbos? May one derive benefit from a cheese dog, which is a grilled hot dog with added cheese and chili sauce? I will be traveling overseas for Yom Tov and Shabbos, and it will be difficult for me to have cooked food ready for an eruv tavshillin. May I use lox as my eruv tavshillin?
