Ok i know this sounds a bit off garage topic, but really its not. We order out a bunch while working on the garage or cars and never have any condiments out there, i do have a frig but really hate to put ice cold ketchup on a nice hot meal. and not sure i wanna microwave it all the time either, so the question is can heinz ketchup stay GOOD if opened and at room temp. I know what the bottle says refrigerate for best results after opening, but every diner i see has them out all day only to return around midnight to the frig than back out around 5am. any food gurus out there know the answer?
