Ordinarily it is not a good idea since bacteria growth can make it unsafe.
It would depend on the room temperature, how long it has been cooking, the size of the pot and how full it is, and whether the lid has been opened since turning off the cooking heat.
If the pot is still hot enough in the morning, it should still be edible.
no due to possible contamination
No. It would not be a very good idea to eat those.
If the meat was in a vacuum-sealed package, then you should not have permitted the meat to get above 38°F, due to possible growth of Clostridium botulinum. For oxygen-permeable packaging, if you can guarantee that no part of the meat got above 40°F for no more than 2 hours, then it could still be safe to eat.The gist of it is that it could be good - or it might not. You will have to make that decision.
I wouldn't recommend having a marinade on potatoes overnight. You can cut your potatoes up the night before and have them soak in water to avoid turning them brown/black. Just make sure the water is about an inch over the potatoes. If you want to marinate, an hour of soak time is good enough for potatoes. It's the oxygen that is touching the potatoes that turns them, so there might be some areas of the potato not completely covered in oil. If you still want to try it, make sure to have an airtight lid on.
No. Stew left out overnight would not be safe to eat, covered or not - unless where it was left out was as cold as a refrigerator.
Yes water can evaporate in a covered bowl and it can even evaporate in a covered bowl in the shade overnight.
No! Throw it out if it was not refrigerated overnight.
Yes it can and plus its a vegetable so obviously you can eat it.
1-4 hrs but no more. Make sure potatoes are covered with water.
If you are referring to unpeeled, uncooked potatoes, you can carry them in a box or a bag. If they are cooked, store them in a covered dish.
if its covered x
Sandy soil helps carrots to grow, but they should also be covered with netting to prevent carrot fly
As bob was poor the meal would have been potatoes carrots cabbage all of which were reasonably inexpensive an the meat would have been a small goose which was the cheapest bird. This would have been covered on a thick flour made gravy. Bread would have also be served to help fill. At that time the meal described was really a banquet for those people as many in Britain were starving, this was to be the message in the story.
