Is oil and salt is used a lot in potato chips?

Potato chips are made by thinly slicing potatoes, frying them in oil until crispy, and then adding salt and other seasonings. The amount of oil used in the frying process can vary depending on the desired crispness of the chips. However, salt is not typically added until after the chips have been cooked and cooled.

The reason for this is that salt can draw moisture out of the chips, making them less crispy. By adding the salt after the chips have been cooked, the salt can adhere to the surface of the chips without compromising their crispiness.
