How do you blanch potatoes before cooking them?

To blanch potatoes before cooking them, first peel and cut the potatoes into evenly sized pieces. Then, place the potatoes in a pot of boiling water for about 3-5 minutes until they are slightly tender. Remove the potatoes from the boiling water and immediately transfer them to a bowl of ice water to stop the cooking process. Drain the potatoes and they are now ready to be cooked using your preferred method.
