Can you freeze raw potatoes and how do you do this?

I assume you want to pre-prepare chips for big family gathering? or for any period of time.

you need good freezing unit
potatoes
chips cutter
knife
3ltr (1 gallon) water with bit of salt and bit of vinegar in it
5kg (11lb) potatoes
table spoon

method:
water solution: to 3ltr (1 gallon) of water add and solve about 6 table spoon of salt and about same amount (6 table spoons) of vinegar (this solution will prevent blackening of the potato cuts), i am adding as well about 3 spoon of sugar to the solution, it allow liquid to cling better to the surface of potatoes, water should be cold, even few ice cubes in it will help
1. wash well your potatoes from debris, sand and whatever junk, remove unsightly, damaged or rotting bits from the potatoes
2. if you have chip machine or slicer - use it! chips should be not thicker than 12mm (1/2"), try not make them thinner than 3mm (1/8"), i do not bother with skinning them, but you may if you have masochistic tendencies. you can do that with knife as well, but will take longer. chips can be cut as straws, plates, sticks. waffle or whatever pattern you have in mind
3. chopped chips drop into the water solution and frequently stir as to allow all surfaces to be covered and prevent browning/blackening of the surfaces (this is oxidation of the surface, it is not poisonous but looks ugly)
4. after all potatoes were used, strain them from water, shake excess water and spread single layer on greaseproof (baking) paper or any other non-stick surface
5. your produce now need to be transferred to the deep freezer and frozen, minimum temperature should be -18c (0f), preffered will be -32c (-25f), if you are living in climate where these temperatures are outside, just put them outside...
6. after deep frozen (about 6h to 12h) divide them and pack them in sealed bags, in suitable portions

that way prepared chips can be stored for months, and if at lower temperature, even for years.

to fry:
have suitable fat at temperature of about 185c (365f), or whatever settings on your fryer is, you do not need defrost them, just directly from the fridge to the fryer, from the moment when they float, about 2min or until golden brown

enjoy!
