The Heinz corporation recommends refrigeration after opening so I do.
Yes to both.
And restaurants dont refrigerate because the turnover time is so short it doesnt have time to go bad. I do know lots of places that use the red squeeze bottles and refrigerate.
What a silly question.
And last week when I went out to eat, I saw a table kill off a brand new bottle of ketchup.
Even if a half filled bottle lasts throughout the day, it'll get killed off the next day.
when I worked at restaurants many moons ago, we would just refill the empty bottles with more ketchup. So gross... I bet some of the same ketchup from when I worked there is still at least a residue in the same bottles.
It's like friendship bread, but more more eerie.
But did you ever fill a completely empty bottle?
At some point diminishing returns is going to get you to toss the bottle.
