Nuthatch said:The answer is.....it depends.
Local conditions make a difference. Arizona in July is not the east coast in May. Humidity and ambient temps, plus how it is stored being non-refrigerated.
Here in the northeastern US, butter stays good on the counter for weeks this time of year. In the summer, definitely not as long.
Soups: it depends on the ingredients. Veggie soup with little fat unrefrigerated is bound to last a day or two, whereas chicken soup I'd eat that day.
Do you remember hard boiled eggs and hiding them for at least a week at Easter? I do. I figure if the shell is intact you might take your chances for at least a few days. But then my Spring is cool and I would put them in my coolest, dark place. Fresh eggs, never refrigerated or washed last longest at room temp. I've kept them for weeks that way.
Run a test in your micro-climate yourself. I imagine ingredients stay longer than cooked products in general.
YMMV

They use water to seal the butter up. Unlimited shelf life (you can do the same by taking the unwrapped butter and placing it in a water filled ziplock bag. Use ONLY salted butter though (with either the dishes or the bag). I have been using this trick for years, and have never had an issue where the butter goes bad.
Cheese can be done similar to this. Cheese (like cheddar) can be placed in a airtight container (zip lock, tupperware, display glass, whatever) and left there indefinitely provided you do one thing, place a sponge of paper towel in the airtight container with the cheese that has a good amount of white vinegar (acetic acid) in it. The fumes from the vinegar will keep the cheese from going bad. The french use this trick to keep the cheese on the counter from going bad. I have gone camping for months and used this trick to keep my large block of cheddar cheese fresh. Three, two pound blocks of cheddar each in it's own 1 gallon zip lock bag will last me a two month excursion, after that they are empty and I am grouchy.

So my question is, is that vinegar necessary for an unopened package of natural (non-processed) cheese? I've heard that mild cheese, in its original package (i.e. unopened), can be aged in the refrigerator for years, as long as it's turned every month or two. [The reason for doing this is that mild cheese is cheaper than sharp, and if you have a bit of money and some refrigerator room, you can make your own aged, sharp cheese.]
Seabird said:I remember my grandmother talking about how they kept softer cheeses like Mozzerella fresh w/o refrigeration in Italy, but for the life of me, I can't recall how. Cheddars, and the like, are a harder cheese, and your answer is great. I wonder if it would work with the softer cheeses, as well. I know that the parmesean and romano cheeses stay fresh in sealed shakers for months in a cabinet, and velveeta comes in packs that can remain unrefrigerated until opened. To be able to keep them fresh longer like that would be most helpful. Thanks, Loup.

I am intrigued. So how long will a rib-eye last if dropped into the Ball jar with the aforementioned preparation?
Does fat content matter?
The Coup Leader said:Here in Canada (Quebec), we have a butter than keeps perfectly well without refrigeration without attracting bugs or anything...
I'll try to find out more info about it.
