Not very long I'm afraid. I wouldn't leave it for more then an hour.
About 10 days at 34F
Yes, you can. some of the Kraft mac and cheese are made to be mirco-waved.
well i would say at the most 10 days but make sure that is is seal with a lid
Even if kept in fridge, only about 5 days.
Don't leave the cheese ball out for more than 2 hours.
not too long
any age. Just as long as they like it.
Until someone puts it back in.
It is a fresh cheese and really should be refigerated to stop it going bad very quickly.
Certainly! A nice chive and garlic cream cheese goes a long way for extra flavor. Be sure to top the wrapped spears with a bit of olive oil so the prosciutto doesn't dry out.
The same lengh of time as the use-by date on the cream cheese, provided the frosting is kept in the refridgerator. (Assuming all the other ingredients have a use-by date that is later than the one on the cream cheese. If any expire earlier, use the frosting by the earliest use by date of any of the ingredients).
As long as the cream it was made with. If you don't have the original tub of cream with the sell by date, only keep it for about 3 days.
They do have expiration dates
