Cook them first if you need to store them in the fridge or freeze them. Wash and slice the potatoes before boiling them until they are soft.

Depending on your desire, mash or slice the potato and sprinkle it with lemon juice. This step will aid in the preservation of the color.

Before freezing, allow them to cool fully before putting them in a freezer bag. In this way, you can freeze them for up to one year.
