The first step is called the blanching process. This is where most of the starch is pulled from the potato and is also the most time consuming. I would do this step a day before you use it.
Take your potato and cut in to desired fry shape while placing in water. When you are through cutting potatoes, you will then agitate the chips by placing your hand in the water and stirring in both directions. You will then drain the water and refill with water. You will see a white foam--this is the starch. You will repeat this until you have almost clear water (the cleaner the water, the better the chips).
Now you will heat a deep fryer to 300°F Use only clean a/v shortening or they will taste like what ever you cooked before! When you fill a fry basket up with chips, make sure it's only half way so that they all go in the grease. Cook for 5 minutes. Place in a container WITH NO LID! for approximately 4 hours or until cool. This will pull all the rest of the starch out that the agitation didn't. This is called blanching. Shelf life 3 days in this state.
Then you will heat the fryer up to 375°F You will then place cooled chips in a fry basket. Cook for 1:30 min to 2:30 min depending on fryer and grease. Watch them--when they float and are golden they are done.
Season with a mixture put together consisting of dash white pepper and some regular ground black pepper and some salt.
Now place your oven rack on to the top shelf or close to, depending how high you stack and place the oven on 200°F This now our melt.
On a baking sheet or heat-safe plate, place 28 oz. of chips (this is approximately 2 home size fry baskets 1 commercial) and 12 oz of evenly mixed Montery Jack and Colby cheese, regular shred. This is about a bowl. Mix cheese on top of chips and place in melt. Watch and see how gooey you want them.
