Potato chips that have never failed – crisp – clean and hygienic

I like crisp potato chips very much, but its not hygienic to sell them outside. So I decided to buy them by myself.

1 Peel and wash potatoes.
2 Slice and wash out starch
3 Pour a lot of oil into the pot.
4 Fried until discolored, with chilli powder and sugar ~delicious to no lower limit, I fried this time older ~do not like too old discoloration can be fished out
