The life of green onions, cilantro, parsley, and fresh herbs can be prolonged by washing them and then putting them in a tall glass of water (filled 1/4 full) in your fridge. It lasts so much longer storing them this way!
Dry Powdered Milk is great to cook with. It's cheaper than regular milk. I like Wal-Mart's Great Value Brand for the price and taste!
Red wine used for cooking can be stored in the refrigerator for quite a while. If you would like to store even longer, freeze in ice cube trays. After frozen dump into zip lock bag. Use a cube as needed!
