a cooked porkchop in a sealed contaier out of the fridge by accident is it still good? If the pork chop was left out longer than 2 hours, there is a risk of food-borne illness if you consume the chop.  Please throw it out! How do you freeze onions? If you want to store for a long period of time, chop or cut and blanch the onions for 2 minutes, cool, drain and pack into freezer bags.  Overwrap or place a second bag around it to prevent onion odours from contaminating other foods.  They may be stored for 6 months. We plan on going on a picnic and have a request for hot dogs. We don't have a grill where we'll be going. Can I boil the hot dogs at home and then store them in a crock-pot to keep them warm and for how long will the hot dogs be good? You may want to serve cold food instead of hot dogs. If transporting boiled hot dogs a short distance, drain and keep hot by wrapping well in insulating towels or blankets. The hot dogs must be kept hotter than 60 degrees C/140 degrees F and should be served within two hours of cooking. I have asked if I could freeze mushrooms and how can I do that and I did not get an answer.  They have been in the refrigerator for 3 days now; are they still good?  Thanks! Button mushrooms can be frozen whole, raw or cooked.
