Sorry I wasn't specific. I want to make potato chips (crisps), not french fries.

I had read on another forum it was best to use 2 fryers, I thought it was strange. I'll go with Aem's method.. Cook the potatoes first at 300- 325F for about six minutes, then remove and drain them while raising the oil temperature to 365 - 375F. Fry again for two or three minutes.

Thx for the tips on the types of oil and potatoes to use.
