The number one food that we throw out is citrus. We have been storing it wrong. We put lemons and limes in the crisper drawer in the refrigerator, where they turn brown and leathery in very short order.
According to this site, we should store our citrus in the fridge, but in a bowl, loosely and not in a container that will concentrate the gasses that citrus gives off. Also, our citrus should not be stored with other vegetables, because it causes them to spoil more quickly. We are seeing that also. So storing our citrus wrong is leading to accelerated spoilage on all of our fresh vegetables. Since we are trying to convert our diet over to primarily fresh foods, increases spoilage in that area leads to added expense right where we don’t need it.
Just thought I would pass this on to you, if you find yourself in the same boat.
