This week I bought a bunch of green beans from Kellogg Valley Farms and froze them. This is how I did it.
Start with the end in mind. Pinch the ends off or use a paring knife. While doing this, inspect the beans for spots that should be removed.
My grandmother would snap the beans in pieces, but I thought it was faster to use my chef's knife and cut them.
Bring a pot of water to a rolling boil then blanch the beans for 2-3 minutes.
Then stop the cooking process by putting your beans into an ice bath. My giant stock pot has a colander inside of it, so I pulled the colander out and was able to pour the beans into icy cold water in my sink.
If you have a salad spinner, use it to dry the beans. If you have a little boy who's willing to help, this is a perfect job for him. We even talked about centrifugal force.
Dump the beans onto a clean, dry towel.
