How to Blanch Green Beans
Salt a large pot of water, and bring to a rolling boil.
At the same time, prepare an ice bath. You will need this to shock your beans and stop them from continuing to cook, when you bring them out of the boiling water bath.
Place your beans in the boiling water and allow it to sit for 2 - 3 minutes. Then remove the beans and drop them in the ice water bath. Allow the beans to remain in the ice bath for 3 minutes or until the beans have fully cooled down.
Remove them from the ice bath and dry them. Set the beans aside for use.
