This is the time of year when the spinach is plentiful. I plant a lot of it, as I like to add it to dips, soups, stews, lasagna, tomato sauce and plan to add it to dog food.
It can be chopped and frozen in water. The water is the important part. It will be good for cooking for months if chopped and frozen in water. Its not good for salad after it has been frozen, however.
Just so you know.
You can chop it fine then put it into freezer bags, cover with water and freeze. I like to use ice cube trays for this so I can add the smaller amounts that I need for things.
I chop it very fine, then fill the ice cube trays with the dry chopped spinach. I then pour water into the trays until they are full and set them in the freezer.
Sometimes, in our freezer, it is hard to find a level surface on which to set several ice cube trays. I have to re-arrange the entire freezer first!
After they are frozen, take them out of the ice cube trays and empty into a large freezer bag. Seal and freeze. Then you can take them out as you need them.
